AS13437 — -Reserved AS-
AS13437 announces 4 IPv4 prefixes covering 2,048 addresses and 1 IPv6 prefixes.
About this network
One netname is IP, another marks a translation pool, and the reverse zone answers undefined.hostname.localhost.
What it's used for
- A small hosting and network company. 2,048 addresses across four IPv4 prefixes, two observed BGP neighbours, and the IPv6 block 2602:f8f9::/40.
Notable
- 23.177.216.0/24 is netname INNO-NAT64-PREFIX.
- 131.143.152.0/22 is netname INNO-CUST-V4-PREFIX.
- Two blocks registered to a second company are netnames RANGE-IPV4 and IP.
- Sampled addresses answered with undefined.hostname.localhost.
- The AS handle recorded in inventory reads -Reserved AS- while the registry names a holder.
Interesting
- A netname declaring a translation pool is a network running IPv6 internally and keeping a small block of IPv4 as the bridge to everything that still needs it. Labelling that in the registry tells anyone reading the record what the block does rather than who owns it, which is the useful thing when the addresses are shared machinery rather than customer space.
- undefined.hostname.localhost is a default that escaped. Some control panel emits it when a hostname field is empty, and here it is serving as the public reverse name for live addresses.
- A netname of IP is the field filled in with the name of the thing it is, by somebody who wanted the form to submit.
