AS13492 — -Reserved AS-

AS13492 announces 2 IPv4 prefixes covering 512 addresses and 0 IPv6 prefixes.

About this network

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.
