Summary

media hosting infrastructure
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.comandet51.rsw6-1-edg.cha.yahoo.com. - The other four answer as
unknown.yahoo.com. - Both
69.147.64.0/23and69.147.68.0/24carry the netnameA-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.

Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
1 upstream, 0 downstream and 2 adjacent networks observed; most-used upstreams first.

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.
