United Kingdom · AI-generated

business uk small

SHIBBOLEET-AS is held by Shibboleet Ltd.

What it's used for

  • The space carries a single IPv4 prefix, 91.241.56.0/24, and one IPv6 prefix, 2001:67c:2e7c::/48, with the netname SHIBBOLEET and registrant Shibboleet Ltd.
  • The inventory consists of 256 IPv4 addresses and 1 IPv6 prefix, observed against 2 neighbours, indicating a small-scale business or internal network rather than a transit or large access provider.
  • Reverse DNS for 91.241.56.64 resolves to nat64.plett.net, suggesting the space is used for network infrastructure or specific service endpoints associated with the operator.

Notable

  • The RDAP registrant Shibboleet Ltd matches the AS holder name, confirming consistent ownership of the address space.
  • The address inventory is compact, consisting of a single /24 block and a /48 IPv6 prefix, typical of a small corporate or service provider 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: 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.
