Summary

Level 3 Communications

United States of America · AI-generated

transit telecom enterprise

PATEAM is the AS handle for Level 3 Communications, a major American telecommunications provider.

What it's used for

  • The address space is registered to COPA with netnames LPL-141-COPA-8-20-65 and LPL-141-COPA-8-38-177, indicating internal corporate or legacy enterprise usage.
  • The AS announces 512 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, a ratio consistent with a transit or backbone role rather than an access network.

Notable

  • The registrant COPA differs from the announcer Level 3 Parent, LLC, reflecting historical ownership or internal allocation structures within the Level 3 estate.
  • Level 3 Communications was acquired by Lumen Technologies in 2021, though the AS remains associated with the Level 3 brand in registry records.
  • The inventory consists of two /24 blocks, representing a small, specific slice of the operator's total address space.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
