AS14196 — YAHOO-CHA

AS14196 announces 2 IPv4 prefixes covering 768 addresses and 1 IPv6 prefixes.

About this network

This one puts the site code in the AS handle, confirming what the hostnames only imply.

What it's used for

• One of a run of numbers a large web company uses for its edge sites. 768 IPv4 addresses across two prefixes, one IPv6 prefix, and one observed BGP neighbour.

Notable

• The AS handle is YAHOO-CHA, and every hostname in this block carries the same three letters.
• Two of the six sampled addresses answer as et18-1.bas3-1-edg.cha.yahoo.com and et51.rsw6-1-edg.cha.yahoo.com.
• The other four answer as unknown.yahoo.com.
• Both 69.147.64.0/23 and 69.147.68.0/24 carry the netname A-YAHOO-US5, which also appears under two other numbers in this run.

Interesting

• The handle settles the question the other cards in this run could only infer. Three letters appear in the middle of every hostname and change from one AS to the next; here the same three letters are in the AS handle itself, so the code is the site and the numbering is per location.
• One netname now covers three separate autonomous systems. The registry recorded a single allocation; the operator split it across three independent announcements and never went back to say so.
• The two router interfaces carry the same names as their counterparts at other sites, digit for digit. Templated naming makes a traceroute across this network read like a table of contents.
• One upstream per site is by design. These announcements exist to be heard locally, and a second path would carry traffic past the site it was meant to reach.
