I have a truly bizarre problem, I can connect to: 18.104.22.168 but not to 22.214.171.124 -- Same mask, same network but somehow if the IP address ends with an even number, I can't connect to it.
Same goes for these:
126.96.36.199 sipgate.co.uk (this is a sip server, not the webpage)
Another clincher is if I restart my internet connection (PPPoA with bulldog) and get an IP address ending with an odd number (e.g. 188.8.131.52) then I can't connect to anything at all.
I have been doing traceroutes and I always reach the gateway but only reach the internet if the IP ends with an off number.
I think my ISP is responsible but they can't find a problem in almost 3 days so far...
Anyone seen something like this before and knows what could the problem be?
