jena76 Posted November 6, 2006 Share Posted November 6, 2006 Does anyone know if it is possible to have two pc's with the same ip address that are not networked? I think they can if they are but not sure Link to comment Share on other sites More sharing options...
GazB Posted November 6, 2006 Share Posted November 6, 2006 Yes of course. For all I know, you could be using the same IP address as me. You can't have duplicate IP addresses or hostnames on the same network though. Link to comment Share on other sites More sharing options...
nick2 Posted November 6, 2006 Share Posted November 6, 2006 I think they can, for example everyone using BT internet will appear (from the internet) to have the same IP address. Link to comment Share on other sites More sharing options...

GazB Posted November 6, 2006 Share Posted November 6, 2006 Well for example, how many people on here will have the IP address 192.168.1.*? A fair few I imagine. IP addresses aren't unique, MAC addresses are. Link to comment Share on other sites More sharing options...

pumatic Posted November 6, 2006 Share Posted November 6, 2006 Many local area networks use unroutable ranges of ip addresses such as 192.168.*.* or 10.*.*.*. On each local network however is a gateway machine which has a routable ip address visible to the internet, anyone on the local network appears to have the same ip address as far as the internet is concerned, some clever jiggery-pokery on the part of the gateway machine using 'port numbers' and translation tables make sure that replies back from the internet end up at the correct machine on the local network.

GazB Posted November 6, 2006 Share Posted November 6, 2006 I dont get it how do certain people get banned then without the others getting banned too? Mod's will answer this, but it goes on factors other than just an IP address. Link to comment Share on other sites More sharing options...
Cyclone Posted November 6, 2006 Share Posted November 6, 2006 If you were banned using an ip address then it wouldn't be the local 192.x.x.x address on your machine, it would be the internet facing ip address that is allocated by your isp. Banning using ip address is a hammer for a nut though. To make it work you have to ban the range that the ISP allocates and that means that you are banning all users from a certain ISP (at least within a geographical area). On a single network it's not allowed (although is possible) to have duplicate ip addresses, as the routers can't distinguish between the machines. The internet can be thought of as a single network, individuals and companies then have their own networks that are seperate from the internet connected through a gateway, it doesn't matter if addresses on different networks are replicated as they aren't communicating directly.

JoeP Posted November 6, 2006 Share Posted November 6, 2006 We rarely apply IP bans because of this - a whole network may appear to the Forum as one IP address, so we can ban users in a number of ways - not just anbsed on IP. However, if we need to we can and will ban IP addresses. Link to comment Share on other sites More sharing options...
