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.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 448 networks and 1,851 prefixes, as published 2026-11-03. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
