Well as the title says, I can't get onto any website which IP begins with 217. Websites I can think of off the top of my head include: www.dsa.gov.uk www.informationcommissioner.gov.uk www.next.co.uk www.marksandspencer.co.uk But it gets a little stranger than that. I'm on a wireless network connected to ADSL with four other computers connected to it. Every single one of these computers can get on above named websites with no problem at all. So, that leads me to believe the problem isn't with the ISP or network, but with my computer. I get the same problem with both IE and Firefox, being either "Connection timed out to (website)" or "Page cannot be displayed". I've run a virus scan with AVG Free Edition and spyware scan with AdAware, both of which come up clean. I'd greatly appreciate any help on this matter, it is rather frustrating. It's really confused me good 'n' proper and I have run fresh out of ideas as to what could be causing the problem. As I say it's limited only to sites which start with that specific IP. All my other browsing works absolutely fine. If there's any essential info I've missed out then I'm sorry; I'll post it up if needed. Cheers in advance.
