Discussion Overview

The discussion revolves around the behavior of IP addresses in an Internet Connection Sharing (ICS) network setup, specifically focusing on whether the client's IP address changes when the computers are networked under a broadband connection with a single public IP address.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant inquires whether the client's computer's IP address will change each time the computers are networked, noting that they have experienced changing IP addresses with dial-up broadband.
  • Another participant suggests checking the IP information using the winipcfg command, expressing uncertainty but indicating that their experience suggests the same IP is assigned even if it is dynamically assigned.
  • A question is raised about the meaning of ICS, with an explanation provided that it involves software NAT on the host, which typically assigns the same IP to the client, often in the range of 192.168.x.x.
  • Further clarification is provided about ICS being a feature in Windows XP and Windows 98, and a mention of typical IP address ranges used in normal computer-to-computer networks.

Areas of Agreement / Disagreement

Participants express uncertainty regarding the consistency of the client's IP address assignment, with some suggesting it remains the same while others acknowledge the possibility of change. No consensus is reached on the exact behavior of IP address assignment in this context.

Contextual Notes

There are limitations in the discussion regarding assumptions about network configurations, the specific behavior of the ICS setup, and the definitions of terms like dynamic IP assignment. The discussion does not resolve these aspects.

Who May Find This Useful

This discussion may be useful for individuals interested in networking setups, particularly those using Internet Connection Sharing or exploring IP address behavior in home networks.

i've got 2 computers running on a ICS network without a router. I am on broadband with 1 ip address. the host is giving the client a separate ip address. will the clients computer's ip address change each time the computers are networked? because i know when i dial up broadband the ip addresses change i think.

thanks

A simple way to check is go to Start>Run>winipcfg

this will give you the IP information. I'm pretty sure your computer will give the same IP each time though, I'm not positive, but with my experience the computer has given the same IP even if it is dynamically assigned.
 
What's ICS?

Usually in these setups, you're doing some kind of software NAT on the host, and it will generally give the same IP to the client, often something like 192.168.0.1 .

ICS is internet connection sharing, made big with XP, available for windows 98.

A normal windows network, computer-to-computer, would use a variation of the 192.168.0.1 IP, although, he is using a router and they can be a lil different, chances are he is still running a class c IP though.
