isp regional uk residential

SPILSBY-AS is operated by Spilsby Internet Solutions.

What it's used for

  • The address space carries residential and business internet access for the Spilsby area in Lincolnshire, as indicated by the netname UK-SPILSBY and the registrant "Terence Froy trading as 'Spilsby Internet Solutions'".
  • The AS announces 1024 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with 1 observed neighbour, indicating a small regional access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and local business connections served by a community-focused internet service provider.

Notable

  • The RDAP registrant matches the AS holder, with the netname UK-SPILSBY registered to "Terence Froy trading as 'Spilsby Internet Solutions'".
  • The address inventory is compact, consisting of a single /22 IPv4 block and a single /32 IPv6 prefix, typical of a small local ISP.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
