Re: ip adress config/dns server

When using a static IP you must also get the DNS server addresses from your router's manufacturer. the primary/secondary DNS for D-Link routers are respectively. contact the customer support line of your product or do a Google search for"_______ dns" (____ being your product name)

Ip address dynamic

Dynamic and Static addressing are the two main methods used for IP address assignments. Dynamic IP addresses are automatically obtained and nothing needs to be done on the user end. However, Static IP address information must be configured manually. If you do not have a router, you need to input your static IP information directly into your Apple Macintosh.

Click "Apple > System Preferences." Click the "Network" icon. Click the "TCP/IP" tab. Choose "Manually" in the Configure drop-down menu. Click in "Show" and choose your Ethernet device. This is usually called Built-in Ethernet. Enter your IP address into the IP Address field. Enter the Subnet Mask into the Subnet Mask field. If your service provider did not provide you with one, use the default of "". Enter the Gateway address into the Router field. Enter the DNS Server into the DNS Servers field. Two should have been provided to you. Push the "Apply Now" button to confirm changes.

IP Conflicts in a work place

An IP address conflict occurs when two computers on a LAN or the Internet have been assigned the same IP. IP conflicts between two computers normally render either one or both of them unusable for network operations.

How IP Address Conflicts Happen

Two computers can acquire conflicting IP addresses in any of several ways:

· A system administrator assigns two computers on the LAN the same Static IP Address.

· A system administrator assigns a computer a static IP address within the local network's DHCP range (dynamic IP range), and the same address is automatically assigned by the LAN DHCP server.

· A malfunction in the network's DHCP server allows the same dynamic address to automatically be assigned to multiple computers.

· An ISP accidentally assigns two customers the same IP address (either statically or dynamically).

· A mobile computer is put into standby / hibernate mode and then awakened later.

Note that other forms of IP conflicts can also occur on a network. For example, one computer may experience an IP address conflict with itself if that computer is configured with multiple Network Adapters. System administrators may also create IP conflicts by accidentally connecting two ports of a network switch or router to each other.

Recognizing IP Address Conflicts

On most Microsoft Windows computers, if you attempt to set a fixed (static) IP address that is already active on the local network, you will receive the following pop-up error message:

The static IP address that was just configured is already in use on the network. Please reconfigure a different IP address.

On newer Microsoft Windows computers having dynamic IP conflicts, you should receive a balloon error message in the Taskbar as soon as the operating system detects the issue:

There is an IP address conflict with another system on the network.

Sometimes, especially on older Windows computers, a message similar to the following may instead appear in a pop-up window:

The system has detected a conflict for IP address...

On Mac or Linux computers, a similar message will normally appear on screen.

Resolving IP Address Conflicts

Try the following remedies for IP conflicts:

1. For networks where IP addresses are fixed (statically assigned), ensure each local host is configured with a unique IP address.

2. If your computer has a dynamically assigned address, releasing and renewing its IP address can workaround IP address conflicts.
3. If your home router is believed to have a faulty DHCP server causing IP conflicts on the home network, upgrading the router firmware may resolve this problem.

Did you configured your wireless modem to be an DHCP server and generate the ip automatically? See your modem configurations and try to use 801b only, 801g and 801n didn´t worked with me.

How do i get my dns numbers from my isp provider,and what is a isp provider.

Best bet is to open up your browser and type in
this will give you your ip address from your isp provider (Internet Service Provider)
If You need some DNS numbers (Domain Name Server), I use open DNS. they are pretty good at keeping out dodgy or rogue sites. Web sites have actual numbers for their address, not names. When you type in, the computer goes to the DNS server to look up the name and get the number (IP address) just like looking up a phone book.
If you choose to use Open DNS as the look up server. use these numbers in your settings.
If you need to put in a gateway (like a front door to go out to the net) you will need to go into your router or modem settings to find this number, Or just call your ISP to get the information. You will need your email username & password before you ring
Good Luck

The adapter seems to connect to the router but says the internet cannot be found. The router seems to be working though....not sure what to check next

go to run and type the command "cmd" hit enter. This will bring up the old Dos looking windows. type in "ipconfig /all" and hit enter. Under Ethernet Controller you should be assigned an IP address. You should also show a Default Gateway, DHCP Server and DNS server. A lot of the time they're the same address as your router. If you don't see these then you need to go to Network Connections and click on TCP/IP and click on properties and make sure that settings for Assign IP Address and Obtain DNS server are set to auto. In the same command window type ping -t or some other address and see if it is making aconnection by showing you a reply from

Get message, Windows has detected an IP address conflict, another computer has same IP address as this one. get this when trying to connect to web after it has connected to dlink that is on the list of...

It appears that at least two of your computers get the identical IP address assigned from your router.

First step: Make sure your router is set as a DHCP server. Log into your router's web interface and check if that's the case. (If you need help with that, tell me make and model of your router)

Second step: Go to the computer that has the IP address conflict.

  1. Click on the start button
  2. Go to Control Panel -> "Network Connections"
  3. You should see an icon labeled as "Local Area Connection" (indicates a wired Ethernet connection) and/or "Wireless Network Connection". Check both - one after the other.
  4. Right-click on the first icon, choose "Properties".
  5. In the next window, in the middle you will find a list of items, one of which is "Internet Protocol (TCP/IP)". Double-click on it.
  6. In the next window, select "Obtain IP address automatically"
  7. Also select "Obtain DNS server address automatically"
  8. Click OK to close this window.
  9. Click OK a second time to close the second window.
  10. If you have more than one connection type, go back to step 4, right click the other icon and choose "Properties". Repeat steps 5 to 9 for this other connection.
If you have any more questions or need assistance in any of these steps, just come back here and leave a comment - I'm happy to help.

Hi Martin,
with all what you say, it looks like that your hardware is ok. That's a good start.
There are several possibilities what can be wrong: either your modem is not configured correctly, or some of the setting in your computer are not right.
Let's start with the computer:
1. open a command prompt (WindowsKey+R), type "cmd" and hit "Enter".
2. In the following window type "ipconfig /all" (there is a space before the "/").
3. Your output should look similar to mine:

Ethernet adapter Wireless Network Connection:
Connection-specific DNS Suffix . :
Description . . . . . . . . . . . : Intel(R) PRO/Wireless 3945ABG Network Connection
Physical Address. . . . . . . . . : XX-XX-XX-XX-XX
Dhcp Enabled. . . . . . . . . . . : Yes
Autoconfiguration Enabled . . : Yes
IP Address. . . . . . . . . . . . :
Subnet Mask . . . . . . . . . . . :
Default Gateway . . . . . . . . . :
DHCP Server . . . . . . . . . . . :

Lease Expires . . . . . . . . . . : Saturday, August 08, 2009 17:32:33

Since the default IP address of your modem is, you IP address has to be in that range:
If your IP address starts with or is, you have a connectivity problem. (Let me know and post your output here, if that's the case.)

Now type in that command prompt "ping" and hit "Enter" - replace the numbers with what you see under your Default Gateway.
My result looks like this:

Pinging with 32 bytes of data:

Reply from bytes=32 time<1ms TTL=64
Reply from bytes=32 time<1ms TTL=64
Reply from bytes=32 time<1ms TTL=64
Reply from bytes=32 time<1ms TTL=64

Ping statistics for
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms

This shows that you can connect to your modem. If you get a "Request timed out." reply, then your computer can not connect to your modem. Also, let me know if that's the case.

Now go back to the command prompt and type "ping" and hit "Enter". My result looks like this:

Pinging [] with 32 bytes of data:

Reply from bytes=32 time=87ms TTL=50
Reply from bytes=32 time=85ms TTL=50
Reply from bytes=32 time=87ms TTL=50
Reply from bytes=32 time=87ms TTL=50

Ping statistics for
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 85ms, Maximum = 87ms, Average = 86ms

This shows two things:
  1. You can get to the outside world
  2. DNS is working properly
Now copy the IP address returned by this command ( in my case) and copy it into the URL bar of your browser. If google shows up, then you have a DNS problem. What that means is that the translation from web addresses ( to IP address ( is not working. Go back and check you entry for DNS servers in ipconfig / all. Is that number identical to your Default Gateway?

How to set up DNS manually:

  1. Click on start
  2. Go to control panel
  3. If your control panel is in classic view click on Network Connections
  4. Right click on your Wireless network icon
  5. Click Properties
  6. Select Internet Protocol(TCP/IP)
  7. Click on the Properties button
  8. Now select the following option: "Use the following DNS server address"
  9. Under "Preferred DNS server address" enter
  10. Under "Alternate DNS address" enter
  11. Click on OK until all windows are closed
Some points on your modem:
  1. If you don't have a manual, you can get it here.
  2. Make sure you have entered your user credentials for Bell (see page 11 in the manual)
Ok - sorry for the long post, but I tried to catch all culprits. If there is anything you don' t understand or it is still not working, let me know - I'm happy to help. If the outputs form the command prompt look very different from mine, copy them and post them here.

Easy way to do that? - Go back to your command prompt.
  1. Type ipconfig /all > C: ixya.txt (hit ENTER)
  2. Type ping >> C: ixya.txt (hit ENTER)
  3. Type ping >> C: ixya.txt (hit ENTER)
  4. Open My Computer, go to your C: drive and you will find a text file called fixya or fixya.txt, which contains all the information.
  5. Come back here and paste the information in a comment.
Let me know if this was helpful and what you found out!

Wrong ip address

On the computer with the "private IP" - which Btw, means it cannot obtain a valid IP from your network - Assign manually an IP of: With a Subnet Mask of: and a Default Gateway of: and a Primary & Secondary DNS Server of:, & respectively. This should work for you.

Short answer? hmmmm

To successfully use port forwarding you must know the IP address of the computer on the INSIDE of your network BUT
your router is most likely using DHCP. This means your internal IP address isn't necessarily static. The "D" in DHCP is for dynamic.

First you need to ensure the the inside IP address of your machine isn't going to change. This can be accomplished 2 ways. 1) assign a static IP to your machine 2) Force specific DHCP IP address assignments by MAC (Hardware) address of your network port - this is the easiest way. Your router does NOT support this option (according to the manual) :-(

So #1 it is...

1) Your router defaults to allocate ALL inside address to DHCP - This will have to change. Alot of routers only use a subset of your internal range (eg: - Yours will too!

Determine how many addresses you wish to reserve for DHCP (for a house 50 should be more than enough). Figure out the range (say -

Also find out the DNS (Domain Name Servers) of your ISP, as you'll be needing them later.

Log into your router and go to Network settings / setup (pages 26 & 27 in the manual) make the changes and restart your router (and computer) you will now be using a DHCP address in the range you just specified! :-)

Now you will need to go to your network settings on your computer and change you r network setting from DHCP to manual. Enter a IP address such as, and your gateway (eg: and your DNS server information that you got earlier.

Now restart your computer to make the changes take effect. We could do something from the command line but I'm trying to keep this short ;-)

If everything is working and you can use the web, check email etc. and your network settings show you are using the manual address you assigned. If you don't have internet review your earlier work (especially the DNS servers) you can always change your computer to use DHCP until your get it resolved.

Congrats most of the tough work is done!

Now you will be using the port forwarding option (Page 28 in your manual) to assign which incoming ports to map to your IP address

Rather than regurgitate other peoples work... see:

I hope this was helpful!
