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?
That is what ARIN has been doing. Those who qualify for /20 can get a /20 where they can eventually get a /19 so that they can announce as /19 to bypass Sprint's discrimination against small businesses.
ARIN implemented a policy in February (based on a recommendation from the Advisory Council) for multihomed organizations. Basically, if you are multihomed and you meet the following criteria: - efficiently utilized a /21 - can justify more address space - agree to return the /21 to whatever organization you received it from within 18 months than you may be issued a /20 from a reserved /19 from ARIN. The idea is that you may announce the full /19 but you cannot use any of the second /20 until you go back to ARIN and justify it. - Kim Hubbard ARIN
