AS12198 — JSMSR-LLC

AS12198 announces 4 IPv4 prefixes covering 1,024 addresses and 21 IPv6 prefixes.

About this network

Four IPv4 /24s, eighteen IPv6 prefixes, and a leased block from an address marketplace.

What it's used for

• Hosting and connectivity. 1,024 IPv4 addresses in four /24s, eighteen IPv6 prefixes, and 26 observed BGP neighbours.

Notable

• 2.27.149.0/24 is netname ipxo, registrant netutils-mnt; Private Customer — a block from an address leasing marketplace rather than one of the company's own.
• 23.162.24.0/24 is registered to Aulthent, a third party again.
• 23.177.40.0/24 is netname PRIVATE-CUSTOMER-US but registered to JSMSR Network itself.
• The IPv6 prefixes are mostly 2602:f919:: /48s and /47s, with one 2406:840:e180::/44 from a different registry's range entirely.
• Sampled reverse names read 64.40.177.23.static.jsmsr.com: the address backwards, as the reverse tree writes it.

Interesting

• Eighteen IPv6 prefixes against four IPv4 /24s is the inversion the address market produced. IPv4 has to be leased a /24 at a time from whoever will rent it, while IPv6 is handed out in quantities nobody has to ration, so the same network is address-poor in one family and extravagant in the other.
• Leaving the address reversed in the host name is the reverse zone's own ordering leaking into the answer. It is generated straight from the in-addr.arpa label without flipping it back.
