Autonomous system
AS7233 YAHOO-
Unclassified ARIN
Summary
Yahoo
hosting legacy
One of Yahoo's smaller autonomous systems, registered under the handle YAHOO-US to
the company's Sunnyvale, California address. Yahoo's main production traffic rides other
ASNs; AS7233 announces only a few narrow prefixes.
What it's used for
- Yahoo's own service and network infrastructure. Reverse DNS in the space resolves to
unknown.yahoo.comhosts behind Yahoo-operated edge routers (fy94.netnaming), so this is company-run datacentre and network address space, not third-party hosting or consumer access.
Notable
- Only two IPv4
/23s and two IPv6/48s are announced, out of98.136.0.0and209.131.48.0— a deliberately small slice of Yahoo's overall address holdings. - The ASN is a 1996 ARIN registration, from the period when Yahoo was still a young search and directory company.
Interesting
- The router names embed site codes such as
sjcandsva, the airport-style shorthand for Yahoo's San Jose and Sunnyvale facilities.
