Summary

Sine Nomine Associates

United States of America · AI-generated

business dns infrastructure

The AS handle SINE-NOMINE-ASSC is held by Sine Nomine Associates Inc.

What it's used for

  • The address space carries infrastructure for a DNS services provider, as indicated by the netname SNA-IPV4 and the registrant identity.
  • The AS announces 256 IPv4 addresses within a single /24 prefix (198.44.193.0/24) and has 1 observed neighbour, a ratio consistent with a small, self-contained business network rather than a transit or large access provider.

Notable

  • The RDAP registrant Sine Nomine Associates Inc. matches the AS holder, confirming direct ownership of the announced space.
  • The inventory consists of a single contiguous IPv4 block with no announced IPv6 prefixes, representing a compact and stable address estate.

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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
