View Full Version : Help - IP address on block lists

For the last week I've not been able to access a range of websites, such as halifax.co.uk, any .gov.uk and quite a few others.

This only happens when I connect the modem directly to the computer, but if I add a router inbetween or use a site such as hidemyass I can connect perfectly. I'm not great on the network side of things but the little knowledge I have led me to think it was possibly a dns or ip address problem.

Rang tech support last night

First time he answered the call, then cut me off
Second time he decided it was a computer problem and put me through to digital home support who wanted to charge me to fix the problem.
Third time insisted on talking to a higher level tech, who still didn't fix it but at least got closer to the problem.

Ran some tracert's to affected websites and each time when it failed the tech support guy said it wasn't virgin to blame, there was a problem with the server of the machine I was trying to get to. When I asked how come he could get on ok, he said 'thats what happens sometimes'.
I told him I thought my ip address had been blocked and he said he didn't think so. I then asked could I be assigned a new IP address to see if it fixed the problem and he said no it was impossible, but the lease runs out on Friday at 23.30 so I should be assigned a new one then, but there was nothing he could do before then.

So after I got off the phone, I did some checks and it turns out the ip range is on some blocked lists, explaining why some sites can't be accessed.

It can't be right that I only have reduced internet access due to this and nothing can be done. What happens if on Friday I'm assigned another IP within the same range?

Anyone got any idea's what can be done please?

The router gets a different IP because it has a different MAC from your internal network card.

Just change the MAC on your NIC or use the router..

The router isn't mine so thats not an option, it was one I borrowed to test something when it started happening.
How do I change the MAC please on the NIC?
Will that change the IP address? I thought that was assigned by Virgin (thats certainly what tech support told me last night)

It is assigned by Virgin, but changing the MAC will force them to issue a new IP as their system will assume a new device has been plugged in.

A new MAC will force a new IP lease, to change it it depends on the NIC, try searching with google

Begs the question though as to why an IP block would be in place or even possible over many websites, you'll probably find that it's a current routing problem with the IP address block

You may find they are running something similar to peerblock. If an ip has been used by a snooping firm at anytime then it will will end up on a blocklist, trouble is when the ip addresses get reassigned some poor user gets stuck with an iffy ip.

Sorry, but seeing your IP address on a block list does not explain the issue.

You are able to get to the sites with a direct connection to your modem, but are having problems with your router. Whilst you would be on a different IP address for the direct and then routed connection, the address assignment would be in the same subnet.

I'd suggest, as has others, that there is a local problem with your router.

IP address block lists are generally used by email network systems for SMTP traffic, not websites using port 80, 8080 and 443.

Whilst the direct connection route solves the problem, I suspect something in your router is the issue.

Can you provide a link to one of the block lists, obviously editing out your IP address. :)

Changing the mac on the router aint gonna do any harm to the router anyway. The guy would not even know as he would have to power cycle the equipment anyway to get his kit to work

You have that the wrong way round, when going through the router, everything is fine. When directly connected to the modem is when i get the problems :)

I can't post anthing until I get home around 6 but will do then

Never trust pings, they're low priority on most networks and on many are totally ignored with no response.

For example Halifax works for me fine yet the final ping still shows as unreachable ;)

yes, but in my case the site won't load either - bit unsure of what other tests to do to fault find?

This is exactly what I get when I try www.halifax.co.uk

The connection was reset

The connection to the server was reset while the page was loading.

* The site could be temporarily unavailable or too busy. Try again in a few
moments.

* If you are unable to load any pages, check your computer's network
connection.

* If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.

Its teh same with IE or google chrome

Kymmy
20-07-2010, 23:17
You sure it's not a firewall issue? You have turned it off to test? Just that the router will give you a local trusted gateway where as a direct modem connection will give you a WAN gateway

20-07-2010, 23:25

"Reply from 62.172.161.126: Destination net unreachable."

This gives clues.

Colin, can you try and reduce your MTU on your PC? It may be too high. Your router will have its own MTU set and will be different from your PC's MTU which could explain why you get problems on one but not the other.

Yes, spot on, much better idea. Don't ping Halifax or OPSI though, their servers don't respond to pings. Why did you pick those ones? Can you not get on their websites? Out of interest which websites can't you get on to? A tracert to a problem site might also shed more light on things. It still might be worth dropping your MTU and trying to access Halifax or OPSI.

Zing, in all examples posted all addresses pinged are being resolved correctly. Unless the OP can provide an example of a ping to a website that doesn't resolve then this isn't a DNS issue.

I used those as they are ones that don't load, some others with tracert's below (none of these load in browsers)

If I go through a site such as http://www.hidemyass.com/ they all load perfectly fine.

Hmmm, I get exactly the same tracert's to these sites and I can't ping them either but I can browse to them. I don't think the tracert's are telling us anything to be honest. Can you try "telnet www.natwest.com 80" from a command prompt and then "GET /private.ashx" then hit enter when you are directly connected to your modem? If you get raw HTML then the problem could be with your browser. If you get a timeout or, even better, an error then it might help tracking this down. It might also help to give us "IPCONFIG /ALL" output for your active network connection when directly connected, don't worry about masking out MACs it's only cable modem MACs that are sensitive data.

ok, tried changing the MAC and didn't make a difference (or change IP)

using http://www.blacklistalert.org/ I get the following result
not sure if it means anything



tracert shows the following

Yeh, that is a problem. Take a look:

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

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/12/33667707-strange-routing-issue-slow-web-acces.html

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.
