An AS handle with a number in it, and two netnames that count different things.

What it's used for

  • Business connectivity. 512 addresses in two /24s with three observed BGP neighbours and no IPv6 announced.

Notable

  • The AS handle is LEXICON4800, the company name with a four-digit number attached.
  • 69.85.91.0/24 is netname LI-308, and 172.99.195.0/24 is netname LEX-BIZ-01. Both are registered to Lexicon International Inc.
  • Three neighbours for 512 addresses.

Interesting

  • Three abbreviations of one company appear in three fields: LEXICON in the handle, LI in one netname, LEX in the other. Nobody enforces consistency across these records, so each one reflects whatever the person filling in that particular form felt like typing.
  • LEX-BIZ-01 is the more informative of the two, because it says what the block is for. Splitting business addresses into their own labelled range is how a small provider keeps customer space separate from its own, and the 01 says there was expected to be an 02.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-28, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 2026-10-29. 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.
