Summary

The netname describes a block half the size of the one actually announced.
What it's used for
- A credit bureau's network, named after an acquired fraud detection company. A single IPv4
/23announced from the United States, no IPv6, and one observed BGP neighbour.
Notable
- The netname ends in a prefix length of twenty-four while the route carried in the routing table is a
/23, so the registry records half of what is announced. - The AS handle names the acquired brand and, in one registry's record, appends this AS number to it.
- The registrant is the parent company, which appears nowhere in the handle or the netname.
- Routing history for this number begins in 2007, later than most of its numeric neighbours.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- A netname naming a smaller block than the announcement usually means the allocation was extended and the label was never rewritten. It matters, because tools that trust the netname will resolve only half the addresses to this organisation.
- Every identifying field here points at a different name: the handle at a fraud detection product, the registrant at a credit bureau, and neither at the other.
- Five hundred and twelve addresses behind one upstream, for a company holding financial records on most of a country's adults, is a small and singular public footprint.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
