Summary
Yahoo
business content edge
YAHOO-INZ is the AS handle for Yahoo, specifically designated for its New Zealand edge infrastructure.
What it's used for
- The address space carries Yahoo's internal edge services, evidenced by reverse DNS entries such as
lo0.pat2.inz.yahoo.comandunknown.yahoo.com. - The AS announces 256 IPv4 addresses across 1 prefix and 2 IPv6 prefixes, while maintaining only 4 observed neighbours, indicating a small, dedicated corporate edge site rather than a transit or access network.
Notable
- The registrant for the announced prefix
27.123.43.0/24is listed asYAHOO INC; IRT-YAHOO-AP, which aligns directly with the announcer's identity. - The inventory consists of a single /24 IPv4 block and two /48 IPv6 blocks, representing a finely subdivided internal corporate estate for a specific geographic edge location.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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 1,771 prefixes, as published 2026-10-15. 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.
