    Oh really? When I plug different equipment in, my ip changes to 10.x.x.x wonder why that is then?

    what equipment ?

    and are you telling me your external IP is now 10.x.x.x, it is more likely that your internal IP is 10.x.x.x

    Equipment, well that would be showing the STP a new router or plugging a pc directly in, as the STP sees different mac addresses.

    Internal addys on my network all begin 192.x.x.x

    I see.

    Well, I could upload one tonight.

    But it's of more importance to figure out how to get my STB to accept a new router. I've tried all manner of switching router, STB off, pc off in all sequences etc.

    Calling Virgin Media is hopeless, they don't know what I'm talking about.

    Did you turn off the MAC spoofing yet? Tried to reset your router to defaults? Can you ping 192.168.100.1?

    If you visit 192.168.100.1 which is the usual IP for the cable modem's webpage, THAT will have a 10.x.x.x IP address.

    Your router connected to the cable modem will not.

    If you plug some "equipment" into your LAN, you may very well get a 10.x.x.x IP address, if that "equipment" is running a DHCP server which is configured for the 10 network.

    Inside the NTL/TW/Virgin/whatever-you-wanna-call-them network they can use the 10 network, but only if its never intended to go to the internet. As your cable modem itself is never intended to go to the internet, it can have one.

    Your router, cannot have one, on its internet side.

    If you want one on your LAN side, go for it.

    Visit your router's webpage on its LAN IP, and go change its settings.

    As a 10 year IT professional, now 7 of it as a network engineer, incl three years supporting cable modems at Telewest and the commensurate qualifications (eg you should believe me when I say this) it doesn't matter in the slightest and the only reason to change it, for a home user, is cosmetic.

    So sure, go ahead, change it if you want, can't hurt.

    Ok, well let's stop talking about my internal network, pinging this or that. My Lan is fine, nothing wrong wiht it. Of course I can ping and access it, I've changed nothing about my internal network, only trying to change routers.

    My Wan addy does indeed change to 10.x.x.x, where it is usually 80.x.x.x which is the ip for my internet connection.

    Router defaults do not need resetting, there isn't a problem with my router, just virgin media isn't easy to use when you change equipment. Virgin uses two dhcp servers per area, which may be why there are the different ranges. Mac addy is back to where it was so my old ip is back.

    But the mystery remains of how one uses a new router.

    yeah listen to zoon we learned that back in cisco.. 10 is reserved as is 192, you'll never see that as your address outside your lan.. let's not get into the osi layers either- keep it simple lol the layers can get really bucktooth

    been years since I got my ccna- 2001 to be exact.. but I know you'll never get that address on the net

    maybe you should call your isp and see if they'll assign you a new ip.. but remember the isp sees all so your porn activity will come up unless you are bouncing through proxies

    ?

    Cable or ADSL from Virgin?

    If it's cable it should go:

    cable from wall - VM supplied modem - Router - PC's etc

    The VM modem will get an IP address from VM & will probably be in in the 70.x.x.x-80.x.x.x range (as that's what they've been assigned by RIPE).
    You can set your router to issue 10.x.x.x IP's internally if you like.

    DSL from Virgin.

    My switch does the internal IP's, not my router, that's just for connection outside. Like I said, not interested in my internal network as there's no issue with it.

    I have no idea what a ccna is, but I googled the term : 10.x.x.x ip addresses.

    First page I got was this: http://computersoftware.suite101.com/article.cfm/ip_address_lookup

    Relevant info:
    "Computers that are on a home network or behind a firewall may receive what is called a "private IP address". These are blocks of IP addresses that operate only in private networks and do not work on the internet. The IANA (Internet Assigned Numbers Authority) reserved these blocks of IP addresses for use in certain internet functions such as routing and device communication. Private addresses can be any of the following:

    10.xxx.xxx.xxx

    172.16.xxx.xxx - 172.31.xxx.xxx

    192.168.xxx.xxx "

    QED

    That reminds me, I've gotta take my CCNP exams this year, before my CCNA expires.

    Anyway back on the main topic.

    DSL meaning what? DSL meaning Cable Modem (which is PPPoE) or DSL meaning ADSL (which is PPPoA)? They are both types of DSL technology, and I've been assuming thus far that you're on cable, so if you're not, it may explain why what we're saying and what you're seeing when you try it, isn't matching up :)

    cheeky fker. I took my ccna but never took a job in networking, I'm not afraid to admit that at all.

    I've said countless times I know the difference, I've already said my internal ip is 192.x.x.x, there is nothing wrong with my lan, the wan IP DOES go to 10.x.x.x, I'm not saying you're all wrong, wheather you like it or not I'm telling you what my ip changes to, WAN IP not LAN IP, the LAN IP does NOT change as I have done nothing to my LAN as I don't need or want to. Perhaps either you can't read, don't know the difference yourself or are just taking the piss. Maybe a screenshot will show you that the wan ip has nothing to do with lan ip.

    Well it is cable, and the wan IP does change to an ip you lot don't like. I don't know why, it may explain why I can't get a connection when it changes to that, so I'll need to work this out as if my router fried, I'd need to know how to get Virgin to like a different router, because when they see a different MAC, things stop working so well.

    Can you describe the way you've got things connected?

    Sounds like you've got too many routers setup
