There's no such thing as IP space fully routable worldwide. Somewhere there's a poorly run network with oudated bogon filters, NAT'd IPs (yours) that someone pulled from their nether regions rather than RFC1918, or a host of other issues that result in your IPs not being reachable from somewhere. Now, I'd expect any IP space an SP assigned to you to be "pretty much fully routed" before you even have them (since you said this is PA space...PI could conceivably take some time to get upstreams to update prefix lists after they're made aware of the prefixes you intend to announce). Unless it's an issue of your provider passing on "new IANA->ARIN" space like something from 72/8 or a similar block. In that case, you're pretty much SOL. Start trying to contact the NOCs of the various networks that need their bogon filters updated. Maybe suggest your SP do the same on your (and their other customers' behalf). > Note: I would post the /24s, but I don't want to call negative attention to > a SP that might be doing his/her job just fine and I just have unrealistic > expectations.. How about you post the /8 they're from (if you haven't already). -- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net| _ http://www.lewis.org/~jlewis/pgp for PGP public key_

Thanks for the private responses I received! Turns out it was a AS append problem... Michael Quick question for the group.. How long should I be patient to wait for some /24s to become fully routable worldwide? None of the addresses are mine, they came from the upstream (only one provider) They are all part of the upstreams IP space, and I had assumed that they would have kept them as part of a larger block and just blackholed into their network.. Instead it seems that route filters had to be propagated WW before the traffic would leave a given AS.. I can reach the nets now (after the first day) from most of the ASs out there, as seen from traceroute.org... But, as my luck would have it, the two nets that I connect from can't get there (die at the handoff to the next AS). I have confirmed this from other people on a few other ASs as well. It has been two days now.. I don't want to be one of those PITA customers you guys get tired of, but I have work to get done.. How long should I sit on my hands? Note: I would post the /24s, but I don't want to call negative attention to a SP that might be doing his/her job just fine and I just have unrealistic expectations.. Thanks in advance! Michael
