residential isp dsl voip

UKSCOMMS-AS is operated by Structured Communications Limited.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries such as 31-169-114-0.dsl.structuredcommunications.co.uk and unassigned-0-106-87-95.structuredcommunications.co.uk.
  • The AS announces 6144 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining 32 observed neighbours; this ratio indicates an access network providing connectivity to end-users rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs, fixed telephone lines, VoIP systems, and web hosting services, consistent with the operator's role as a communications solutions provider.

Notable

  • Registrants for the three largest prefixes are STRUCTURED COMMUNICATIONS LIMITED, while the smallest prefix 185.139.36.0/22 is registered to LA ICT Services Limited under netname UK-LAICT-20160217.
  • The address inventory is composed of four distinct IPv4 blocks, with the largest being /21s and the smallest being /22s, reflecting a mixed acquisition history.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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 1,851 prefixes, as published 2026-11-03. 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.
