AS14021 — PSECU

AS14021 announces 3 IPv4 prefixes covering 1,024 addresses and 0 IPv6 prefixes.

About this network

The same mail server name answers at the same offset inside two different providers' blocks.

What it's used for

• A credit union's network. 1,024 addresses across three IPv4 prefixes, with one observed BGP neighbour and no IPv6 announced.

Notable

• 63.116.229.190 and 65.207.1.190 both answer as mail.psecu.org.
• Both of those blocks carry the two-letter netname VZ and are registered to the credit union.
• 50.202.112.0/23 carries CCCH3-4 and is registered to Comcast Cable Communications, LLC.
• Nine addresses were queried for reverse DNS and two returned a name.

Interesting

• Two blocks, from what were once two different carriers, each with a mail server at the same last number and the same published name. Someone laid out the second network by copying the first, offset for offset, so that a failure of one carrier changes nothing about where anything lives.
• Holding two blocks in the member's own name and a third in a cable provider's name is the usual split between space that follows the organisation and space that follows the circuit. Only the first kind survives changing provider.
• A financial institution publishing exactly one name, for the one service that has to be found by strangers, is the correct amount to publish. The other seven addresses sampled gave nothing away.
• One observed upstream understates the arrangement, since a credit union's real dependencies are private links to payment networks that never appear in public routing.
