Summary

Kayak

United States of America · AI-generated

business corporate travel

KAYAK- is the autonomous system for Kayak Software.

What it's used for

  • The space carries corporate infrastructure, evidenced by the netname KAYAK-US and registrant Kayak Software; KAYAK Network Operations.
  • The AS announces 512 IPv4 addresses across 1 prefix with 2 observed neighbours, indicating a small internal corporate estate rather than a transit or access network.

Notable

  • Registrants align with the announcer, listing Kayak Software and KAYAK Network Operations for the sole prefix.
  • The address inventory consists of a single /23 block, reflecting a compact, self-contained corporate footprint.

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.
