Summary

AS13492

unknown · AI-generated

business enterprise hosting

The registry lookup for the autonomous system failed, so everything known here comes from the two blocks it announces.

What it's used for

  • A network announcing two /24s. 512 addresses, two observed BGP neighbours, and no IPv6 announced. The country of the blocks is recorded as unknown.

Notable

  • The holder lookup failed, and the AS handle recorded in inventory reads -Reserved AS-.
  • 207.250.99.0/24 is netname TWTC-AHNI and 216.37.59.0/24 is netname NFRAME, both registered to the same healthcare network company.
  • All six sampled addresses answered: three as 207-250-99-64.static.ctl.one and three as IP-216-37-59-64.nframe.net.

Interesting

  • When the record for the number itself is missing, the prefixes are the evidence. Two blocks, two netnames naming two different carriers, one registrant naming the customer of both. That is enough to know what this is without the holder record existing.
  • The two reverse zones are run by different providers and disagree about capitalisation and about whether to prefix the address with anything. static in one says the address does not change; IP- in the other says only that a template needed a leading letter.
  • One of those domains is four characters plus a suffix, a carrier compressing its own name to keep generated hostnames short. Reverse zones are the one place a company optimises its domain for length.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,783 prefixes, as published 2026-10-17. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
