Summary

Hyperoptic

United Kingdom · AI-generated

residential isp fiber uk

BCUBE-AS is operated by Hyperoptic Ltd.

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS entries pointing to bcube.co.uk and registrant netnames such as UK-BCUBE-19900326 and UK-BCUBE-19900110.
  • The AS announces 141,312 IPv4 addresses across 42 prefixes and maintains 92 observed neighbours, a ratio consistent with a regional access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for Hyperoptic's fibre-to-the-home service, which provides high-speed internet to residential customers in the United Kingdom.

Notable

  • All sampled registrants are listed as Hyperoptic Ltd, aligning with the AS holder and confirming consistent ownership of the announced space.
  • Hyperoptic Ltd was incorporated in 2010 as bcube Limited and subsequently rebranded to Hyperoptic, explaining the retention of the bcube domain in reverse DNS records.
  • The inventory includes a mix of legacy and modern prefixes, with the largest block being 143.58.128.0/17, reflecting the company's growth and acquisition of address space over time.

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: 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.
