not sure if it means anything

tracert shows the following

Yeh, that is a problem. Take a look:

Code:

> cpc2-sund8-0-0-cust***.know.cable.virginmedia.com
Server:  ******
Address:  192.168.1.1

Non-authoritative answer:
Name:    cpc2-sund8-0-0-cust***.know.cable.virginmedia.com
Address:  213.106.***.255

> 213.106.***.255
Server:  ******
Address:  192.168.1.1

Name:    cpc2-wear8-0-0-cust***.midd.cable.ntl.com
Address:  213.106.***.255

The reverse DNS does look a tad borked, but not sure if that's the reason why you can't hit stuff.

Your IP address doesn't appear to be on a block list though

how can you change the MAC address and not get a new IP? I was under the impression IP addresses are assigned to the MAC address so when you change a new IP is issued?

I've never seen it work like that, I can unplug my router and connect directly to the modem with any PC or device and keep the same IP.

Is your router's wan MAC address cloned to be the same as the NIC in the PC your connecting straight to your cable modem?

AFAIK this would also happen if the DHCP server for your area has very few spare/released IP's in it's pool.

Again, AFAIK, the DHCP lease is MAC tied, if you reconnect with the same MAC address within the lease time of your original IP, you will get the same IP back again. However if there aren't any spare IP's in the pool and either someone else requests an IP or you request one using a different MAC address, then you may get the one back you've just released. It will do this as it's the only IP it can give you.

but he says its never changed you can assume by what he typed its not just a one off?

Would unplugging the modem from a router release an IP? I thought IPs were leased for a period and would still be tied to the MAC until a physical release was issued? if its still leased surely it can not be allocated to a different Mac

Probably, yeah.

Just unplugging the cable wouldn't, the DHCP server would need to see a DHCP release datagram. Power cycleing the cable modem will probably do this I assume. On the DHCP lease period, as unlikely as it is, the DHCP server could hand that IP out even if it's still within the lease time of a previous lease. To my mind it all hinges on the IP being marked as released.

Thanks to everyone for their help

On my 5th call to tech support, they finally gave me a proxy address to use that is allowing me to access any site. In case anyone else hits this problem its

webcache.virginmedia.com port 8080

Kymmy · 27-07-2010, 20:42

Which is just a workround of a fault.. Way to go VM, if it doubt ignore the problem and bodge it

colinsunderland · 28-07-2010, 05:20

yes, thats what I thought actually, but after all the hassle I've had with them it was better than nothing

Hi, just noticed this thread, it looks like the same problem as a number of others are having, seem this thread and also a post on community.virginmedia.com

http://www.cableforum.co.uk/board/12...web-acces.html

http://community.virginmedia.com/t5/...ad/td-p/100491

Judging by your username you are probably local to us also (TS12 area - Saltburn??)

I too got fobbed off with using the VM proxy which was fine over the weekend until I tried to sign into Xbox live, which wont connect. My other main problems are FTP access to my website's server is unstable - disconnects after around 20-30 seconds and very slow to connect. Also unable to login to my website admin tools which uses a non standard port (www.mywebsite.com:8565/cpanel)

Going to have to ring them up again I think, I'm at work all day but will call them tonight.

OK, tried 3 times to call VM on 150, first time on hold for 12 minutes and then line went dead. 2nd time the guy went silent on me and then hung up. 3rd time line went dead after 26 minutes of being on hold. I gave up. Not good enough, not sure what to do now, I need it fixing to administer my website!! Damn.

One thing I did notice was when ringing the support before you get put through to the call centre a recorded message says something like "sorry your having a problem in the TS22 area, its being looked into and will be fixed asap" Seems a bit strange as I'm not TS22 (thats billingham area I think) I'm TS12. Hopefully they meant TS12 and I'll wake up to find it fixed tomorrow.
