Yes, however we recommend using the following procedure is the only way you can do so without a block of IP addresses. The example below is for instances where you have multiple public IP addresses that are not in block form. For our example the ISP has given us 3 Public IP addresses. One goes to the FTP server, Web Server, and the Router. You can setup the router for whomever your ISP is. If you have a dynamic IP address and you're unsure on the setup, please see the article on setting up the router with a static IP address. If you have a static IP address please our article on setting up static IP addresses with the router, and it will describe how to setup the router with a static IP address. Once the router is setup, it will provide the 3 PC's (In our example) with internet access. The remaining two public IP addresses should be assigned to the WEB Server and the FTP server. Note - The Web and FTP servers will not be on the Local Area Network of PC-1, PC-2, and PC.

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.

Ip address


Find my IP Address
Click start type cmd press enter you will be in DOS mode
type in ipconfig press enter you will see all of your internet connection details type in your default gateway ip adress into your internet search should read something like 10.0.0.138
Your IP Address should be thought more as your computer's phone number than it's address, if you have multiple connections, you have multiple IPs if you dont have a connection, you dont have an IP.
Without further delay If you need your computers IP address:
This will work in almost every case, it simply requests the website's server to tell you what your IP is.
http://whatismyipaddress.com/
I have included a link to make things easier.
If you are in a network and need your computers local address.
Hold the windows button (looks like the windows banner, usually between left ctrl and left alt) and press 'R'.
A box will display, and type in "cmd.exe" and hit enter.
The 'command prompt' will display, a black screen with white lettering.
Simply type in ipconfig. This gives information on all your internet connections.
Look for the line "IPv4 Address".

If you need to find the IP of a current connection you can type (from the command prompt) "netstat".
This will give you all your current connections.
To identify a specific one, the easiest way is to run it before you establish the connection then again afterwards.

How to Change IP Addresses
Your IP address is a series of numbers that identify your specific computer on the Internet.
If, for some reason, you want to change your IP address, you can do so without going into the command prompt.Click "Start," "Control Panel," "Network and Internet" and "Network and Sharing Center."
Click "Change adapter settings."
Right-click the network you want to change and click "Properties."
Click the "Networking" tab.
Put a check either next to Internet Protocol Version 6 (TCP/IPv6) or Internet Protocol Version 4 (TCP/IPv4) and click "Properties."
Click the radio button next to Obtain an IP Address Automatically if you want Windows to assign one, or click "Use the following IP address" to manually change it.
Enter the requested information and click "OK."

How do i split out multiple static ip's


You need to attach a DHCP-server to the hub/switch, and configure that DHCP-server to "reserve" a specific IP-address for the MAC-address for the network adapter inside each of the computers that is to receive a "static" IP-address.
For a DHCP-server, you can connect a "cross-over" Ethernet cable from one of the switch-ports to one of the LAN-ports on any "home" wired router. That "home/SOHO" router will become the DHCP-server for all the computers connected to the switch.

Where is IP address for the MFC-7220 printer


Network printers do not have a set IP address, you need to configure the printer with an IP address that uses the same range of IP addresses as your network.
The IP configuration is normally done through the printer's Menu on the printer's buttons.
If your are using a network IP range 192.168.0.*** that your wireless router issues automatically then select a fixed IP address on your printer above the number of computers that is installed on your network. (ie if you have 10 computers the make the printer's fixed IP address say 192.168.0.30) so the wireless router cannot issue a conflicting IP address.
When you install the printer driver on each computer then go to the Printer Properties - Port tab - click Add Port - IP port and enter the printer's fixed IP address and printer name.
Do a test print to check if your computer connects to the network printer.

What is ip mapping? and how i can use two or more internet connection at a same time?


IP mapping is the practice of recording multiple devices within a network by their IP address to assist in troubleshooting.

You can connect multiple devices to one modem using a router. The router splits and directs the signal from the modem. If you are using auto-detection for internet connection, they should pick up their addresses automatically, however you will need to have someone set up the router to path properly.

Can you tell me what an ip addresse is im trying to connect to xbox live and it keeps asking for ip addresse


Every device connected to the public internet is assigned a unique number known as an internet protocol (IP) address. IP addresses consist of four numbers separated by periods(also called a 'dotted-quad') and look something like 127.0.0.1 

since these numbers are usually assigned to internet service providers with region based blocks, an IP address can often be used to identify the region or country from which a computer is connecting to the internet. an IP adress can sometimes be used to show the users general location because the numbers may be tedious to deal with, an IP adress may also be assigned to a host name, which is sometimes easier to remember hostnames may be looked up to find IP adresses,and vice-versa. at one time ISPs issued one IP adress to each user. These are called static IP addresses. beacuse there is a limited number of IP adresses and with increased usage of the internet ISPs now issue IP adresses in a dynamic fashion out of a pool of IP addresses (using DHCP). these are referred to as dynamic IP addresses. This also limits the ability of the user to host websites mail servers, ftp servers, etc. in addition to users connecting to the internet with virtual hosting,a single machine can act like multiple machines (with multiple domain names and IP addresses).
