About this network

Three blocks, three carriers, three completely different ways of writing the same company's name.

What it's used for

• A technology services company's network. 1,536 addresses across three IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• 70.251.172.0/22 is netname SBC07025117200022050926131857.
• 12.39.162.0/24 is netname DIVERSIF236-162.
• 67.217.159.0/24 is netname 67-217-159-0-0.
• All three are registered to the same company, spelled in mixed case twice and capitals once.
• First seen in the routing archive on 2020-08-16, recent for an autonomous system in this range.
• Nine addresses were queried for reverse DNS and none returned a name.

Interesting

• Each carrier that handed this company addresses named the block its own way. One packed the address, the prefix length and a timestamp into a single digit string. One truncated the company name to eight characters and bolted on numbers. One skipped names entirely and wrote the address.
• DIVERSIF stopping mid-word is a field-width limit from a provisioning system that allowed eight characters, preserved in the public record long after the limit stopped mattering.
• An autonomous system number issued decades ago that only starts appearing in routing recently was held, transferred or simply unused for years before somebody turned it on.
