Summary

National Football League

United States of America · AI-generated

business corporate sports internal

The AS handle NFL3 is operated by the National Football League.

What it's used for

  • The address space carries corporate infrastructure for the league, evidenced by netnames NFL on prefixes 72.46.66.0/23 and 72.46.68.0/23.
  • The AS announces 4096 IPv4 addresses across 4 prefixes with only 3 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

  • Registrants are mixed: NTT America, Inc. holds the larger blocks 204.141.136.0/21 and 204.141.132.0/22 (netname NTTA-204-141), while the National Football League directly registers the smaller 72.46.66.0/23 and 72.46.68.0/23 blocks.
  • The inventory is split between two distinct address ranges, with the NTT America-registered space comprising the majority of the announced address count.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-25, 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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
