Unclassified RIPE
Summary
Name Unit Limited
business norse small
The AS handle NAMEUNIT-AS is held by Name Unit Limited.
What it's used for
- The address space carries business traffic, evidenced by the reverse DNS entries pointing to
service-91-220-143.nameunit.com. - The network announces a single IPv4 prefix, 91.220.143.0/24, comprising 256 addresses, with one observed neighbour, indicating a small-scale business or internal corporate estate rather than a transit or large access network.
Notable
- The registrant for the announced prefix 91.220.143.0/24 is NAME UNIT LIMITED, matching the AS holder.
- The address inventory consists of a single /24 block, which is a compact allocation typical for a small business or specific service deployment.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
