You have 2 IPs:

One for your cable modem, and the other for your PC.
When you unplug your modem, your PC IP stays the same, but not on your modem (refer to your ISP for this). Now if you want to change your IP on your PC, to to the TCP/IP settings for your network interface and set a manual one.

How to obtain public IP from Time Warner


<p>There are two basic types of IP addresses of internet service providers (ISPs) to provide customers with Internet services: a dynamic address or DHCP and a static IP address. A static IP, as the name implies, uses the exact same IP, and you're online all the time. The DHCP IP configuration uses a "stack" of available IP addresses each time a modem is online and an IP address of the network of the ISPs is simply grabs the first available IP address from the stack. The IP configuration of DHCP, then it is very easy for a new public IP address from your provider at any time <br /> <p><br /> <p>1. Unplug the cable modem from Time Warner. Total count of 30 seconds and close. <br /> <p><br /> <p>2. Allow the modem to reboot every five minutes. During this time, goes through the boot cycle, contact your provider and ask for a dynamic IP address. <br /> <p><br /> <p>3. Navigate to the computer's IP Configuration Manager. For most versions of Windows, the easiest way to do this is to open the Start menu, click All Programs, then select "Command Prompt" from the "Accessories" menu (for future versions of Windows, you may need to the right button on the Command Prompt and select Run as Administrator "to show itself sufficient permissions on IP of the computer information). <br /> <p><br /> <p>4. IP address to test your computer by typing "ipconfig" and "Enter" Command to the numbers printed next to "IP address", like "IPv4 or IPv6 address." The number displayed on the public IP address of the DHCP as the modem from Time Warner will receive net. <br />

It probably isn't connect to the outside world. It doesn't know what IP to use on the outside. Call your ISP and see what your IP or if you should just keep in on dynamic and have it autopick up a IP.

Ip 3rd time is chainging.all time speed is going down


what ip are you referring to? most internet service providers provide dynamic ip addressing to their residential customers and dynamic ip addressing means that your ip address will be changed periodically. Static ip addresses (ip adoes not change) is usually provided for business consumers.
as for the speed, if you subscribe to 4Mbps speed package, what it actually means is that you willbe getting UP TO 4Mbps speed. that would explain why your speed goes down. you will not always have 4Mbps.

Your internet service provider only able to change your external ip address. The only way to change it own by using proxy sites or ip hide software's. Online proxy sites are simple and free of cost . But they worked for some periods only. So you can always check your ip is hide or not at Ip-Details.com

Just a bit of explanation. E0 interface is for inside network (LAN interface). E1 is for outside (ISP or WAN physical interface). Dialer1 is for PPPoE (the "actual"/logical WAN interface). The 1.0.0.13 is ISP provided static IP address for the use of the server. This configuration example is for running FTP server, which uses the standard TCP port 20 and 21.

The LAN uses 10.10.10.0 network with 255.255.255.0 subnet for both servers and workstations. All servers within the LAN use static IP address. The router is configured as DHCP server to give out IP info (IP addresses, subnet mask, DNS) to workstations that are configured as DHCP client.

Basically I suggest that you deploy NAT (Network Address Translation) and PAT (Port Address Translation) to setup your own servers behind Cisco router. The NAT is used to translate the ISP's given static IP address to your local IP address. The PAT is used to translate TCP ports (the port 20 and 21) between the two IP addresses.

When using NAT/PAT, keep in mind that the Internet-accessible servers are seen from the Internet as their NAT/PAT-ed IP address (the Public IP address) and not the local IP address (not the Private IP address). This understanding is very important when you or someone need to test connectivity to the server and/or when you need to create filter (access list or ACL for short) to allow only certain incoming traffic from the Internet and block others.

Side Note:
For more info on NAT/PAT concept, check out the following FAQ
»Cisco Forum FAQ »NAT and PAT; Introduction and Implementations

Instruments used in this illustration are pretty much standard for running your own servers. Please note that IP addresses, username, and password are changed. However, you could always modify the configuration to suit your situation.

This sample configuration assumes that you have a block of IP from ISP. There is a dedicated Public IP address for the router WAN interface (the Dialer1 interface) and another dedicated Public IP address for the server PAT IP address. If you only have a single Public IP address for both router WAN interface and server PAT IP address, there are several ways to configure the router.

One way is to use the same command as shown in sample configuration.

view plaincopy to clipboardprint?
  1. ip nat source static tcp 10.10.10.2 21 1.1.1.14 21 extendable
ip nat source static tcp 10.10.10.2 21 1.1.1.14 21 extendable
This one configuration way is suitable when you have static IP address from your ISP and you know exactly what the IP address is. In this case you have the 1.1.1.14 single static IP address for both the WAN interface and Public server IP address.

When you are unsure which IP address you receive from the ISP, or when your Public IP address keep changing; then another way to configure the static PAT is following

view plaincopy to clipboardprint?
  1. ip nat source static tcp 10.10.10.2 21 interface Dialer1 21 extendable
ip nat source static tcp 10.10.10.2 21 interface Dialer1 21 extendable
With situation of dynamic IP address, at some point you still need to know the exact Public IP address you receive from your ISP for server connection testing and production time. To find out, you can issue show ip interface brief command on the router. You will then see the associated WAN interface Public IP address.
