Summary

ANS Communications

United States · AI-generated

transit legacy

A network of ANS Communications (ANS-1699-AS). ANS (Advanced Network and Services) was an early US internet backbone operator that built and ran the NSFNET T3 backbone.

What it's used for

  • Backbone and transit networking, historically part of the ANS/NSFNET infrastructure.

Notable

  • ANS was a pioneering national backbone provider; it was later acquired by AOL and its network passed to WorldCom/MCI.
  • The low AS number reflects an early allocation from the internet's formative years.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
