      IP address question

      [I'm asking this here because the other forums don't get so many visitors. Hope that's OK.]

      If I connect both my PC and the laptop to the net via my router, they both get the same IP address. This has got me puzzled.

      Suppose I installed a web server on both the PC and the laptop and put a different index.html page on each. If you then type my IP address into your browser, which web server would process that HTTP request, i.e. which of my two index.html pages would you see?

      Re: IP address question

      The router is the one with the real IP address. The computers connect to the net via the router, so they end up appearing the same to anyone outside of the home network.

      If you really want to set up a webserver on your home PC then you would need to set up port forwarding to the computer with the server/pages on it.

      But as Sky doesnt supply static IPs it's kind of a moot discussion.

      Re: IP address question

      Its like NTL, if you want an extra IP address you have to pay for an extra one, rip off... when i tried to connect my xbox it wouldnt share the same IP if i had my p on at same time, unless theres someway of fixing that i dont know, but sky must be like that.

      I do not have a Xbox, but if this was the case, surely others would have brought this up. The Xbox works with an NIC, which would have it's address allocated by the router, the same as any PC which may be connected. Some types of cable are/were different in that they would not allow more than one PC to be connected. This may have changed now, but it is not the case with Sky.

      Re: IP address question

      The one that you would see would depend on the port forwarding options you set up in the router configuration. It allows you to "forward" a port from your external ip (the one sky issues you) to the internal ip of either your computer or your laptop (they would probably be in the form 192.168.0.somthing). For a web server you would generaly forward port 80 (this is the default port for a web server).

      About the xbox, it should be issued with an internal IP address just the same as your PC(s). There should be no reason for only one to work at once. There is also no reason to have two external IP addresses. Im not sure if you have to forward any ports for xbox live, have a look on google...

      Virtually all ISPs are like that. You only ever get one single IP address.

      The only way to connect more than one device (PC, Xbox, whatever) at the same time is to use a router (or Internet Connection Sharing).

      ntl used to do a "Broadband & Console Service" which gave you a 2nd IP so you could connect an Xbox/PS2/etc. at the same time as your PC, without the need for a router. However, it was a bit of a rip-off, as it cost the same as just buying a router (but spread over a year). They dropped it eventually. Far far better to just use a router (which is what I always did anyway when I had ntl... never wasted money on the stupid console service).

      As you get a router with Sky, it's not a problem. My PC, Xbox360, Xbox, Wii & laptop have no issues using the net via the Sky router.
