Summary

Cleveland Browns

United States of America · AI-generated

business sports corporate

The AS handle CLEVELAND-BROWNS is held by Cleveland Browns.

What it's used for

  • The address space carries corporate infrastructure for the NFL franchise, with both prefixes registered under the netname CBFL and registrant Cleveland Browns.
  • The network announces 512 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal corporate systems, office workers, and web endpoints for the professional American football team.

Notable

  • Registrants for both announced prefixes agree with the announcer, listing Cleveland Browns as the registrant.
  • The address inventory is compact, consisting of two /24 blocks (64.190.155.0/24 and 137.83.13.0/24) that align with the team's operational footprint.

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: 442 networks and 1,779 prefixes, as published 2026-10-22. 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.
