residential broadband uk telecom

BSKYB is operated by Sky UK Limited.

What it's used for

  • It announces 8192 IPv4 addresses across 1 prefix with 1 observed neighbour, a ratio indicative of an access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for Sky's UK broadband and television services.

Notable

  • Registrants BSkyB Telecoms Support, Sky UK Limited, and Sky UK Broadband Hostmaster align with the announcer.

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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
