Summary

United Airlines

United States of America · AI-generated

airline corporate business internal

The AS handle CONTIN-83-1 is held by United Airlines, Inc.

What it's used for

  • The address space carries corporate network operations, evidenced by the netname UALNET and registrant United Airlines - Network Operations across all sampled prefixes.
  • The AS announces 68,864 IPv4 addresses across 71 prefixes with only 3 observed neighbours, a ratio that indicates an internal corporate estate rather than a transit or access provider.

Notable

  • All registrants in the evidence pack agree with the announcer, consistently listing United Airlines and United Airlines - Network Operations.
  • The address inventory is finely subdivided into numerous /20, /21, and /22 blocks within the 161.215.0.0/16 range, consistent with site-by-site segmentation for a large enterprise.

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 1,783 prefixes, as published 2026-10-20. 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.
