Where's 209.240.157.34 ?
Got a spam advertising a web page there, ARIN claims it's not allocated although all the space around it is. It routes through Tierranet.
[edit]
Perhaps ARIN has reserved the entire /19 for TierraNet, but only actually allocated the lower /20 to them? Perhaps TierraNet is announcing their /20 as a /19 to get past Sprint's route filters?
ARIN policy for initial allocations to ISPs declares that a provider will be allowed to temporarily announce a /19, when they have been allocated a /20.
Well...that explains why they're announcing a /19 when they've been allocated a /20, but it leaves the question "Why do they have machines with addresses in the top portion of the /19 announcement that are not in the /20 they've been allocated?" -Richard
