YAHOO-HK2-AP is the autonomous system for Yahoo in Hong Kong.

What it's used for

  • The address space carries Yahoo's edge and internal infrastructure, evidenced by reverse DNS entries such as et14-1.bas3-1-edg.hkb.yahoo.com and et51.rsw6-1-edg.hkb.yahoo.com, alongside generic unknown.yahoo.com records.
  • The AS announces 768 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, dedicated corporate estate rather than a transit or access network.

Notable

  • The registrants for both announced prefixes are listed as YAHOO INC; IRT-YAHOO-AP, which aligns directly with the AS holder YAHOO-HK2-AP.
  • The inventory consists of two IPv4 blocks in the 180.222.113.0/24 and 180.222.116.0/23 range, along with a single /48 IPv6 prefix, reflecting a finely subdivided internal corporate network.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
