AS18293 announces 2 IPv4 prefixes covering 768 addresses and 1 IPv6 prefixes.

About this network

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.
