Hi everyone, Hope anyone can help me here. My problem is, some of our IP ranges appear to be filtered by some network providers. Could anyone please point me to the right direction or unblock our ranges ? Our ranges are : 202.20.0.0/21 - I believe this does not have any issues 202.68.80.0/21 - some blocks in this /21 have issues connecting to some sites, 202.68.86.0/23 Thanks kindly

Can you give some more information about what sites you're having problems connecting to? If international sites don't work, you should work with your international provider(s) to resolve. If national sites don't work, you should figure out which ISPs are not accepting your advertisements, and contact them. I'd be surprised if national sites aren't working, but international ones are - most providers in NZ are carrying default routes, so even if you weren't going over peering links, you should still be able to access content on/behind those networks. -- Nathan Ward -- Nathan Ward

Your customers are complaining about not being able to see advertisements on the TV3 website? :-) Looks to me like your BGP advertisements are a bit wierd, but it's hard to be sure from where I'm sitting. For example, WIX has 202.68.86/24, and 202.68.87/24. Why are you not advertising that as a /23? APE doesn't have either prefix, or the /23. It does seem to have 202.68.94/23 though, which is in your /19. Both appear internationally as /24s, no /23 - this means that those other NZ networks /should/ see your traffic, unless you have some kind of filtering in place. You don't have strict RPF or anything do you? Do you have routes to reach those networks? I assume so, if you're able to reach them from some of your prefixes. I also notice that subnets of 202.68.87/24 appear on WIX - a /27 and a /28. Are these the customers that are having problems? Aggregation would be good while we're at it: http://www.cidr-report.org/cgi-bin/as-report?as=AS24183&view=2.0 -- Nathan Ward
Hi, I can see some entries via PacNet and some via TelstraClear. 202.68.80.0/21 is via PacNet, 202.68.86.0/24 and 202.68.87.0/24 via TelstraClear. I don't see 202.68.86.0/23 at all. Are you filtering inbound differently on the two different transit providers? A good option is to use route-views.routeviews.org to have a look at what the world is seeing.
