Summary

The Berkeley Group

United Kingdom · AI-generated

business corporate real-estate uk

BERKELEY-AS is the autonomous system for The Berkeley Group plc.

What it's used for

  • The space carries corporate infrastructure for a major UK residential property developer, as indicated by the netname BERKELEY-GROUP and registrant The Berkeley Group plc.
  • The AS announces a single IPv4 prefix, 193.19.89.0/24, comprising 256 addresses, with 0 IPv6 prefixes.
  • With only 1 observed neighbour, the address-to-neighbour ratio suggests a small, self-contained internal corporate estate rather than a transit or access network.

Notable

  • The RDAP registrants for the announced prefix include both The Berkeley Group plc and Telefonica Tech UK&I, indicating a potential relationship with a telecommunications provider for connectivity or infrastructure services.
  • The address inventory consists of a single /24 block, which is typical for a specific site or internal network segment within a larger corporate structure.

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 1,779 prefixes, as published 2026-10-21. 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.
