Summary

Bristol City Council

United Kingdom · AI-generated

government municipal uk internal

BRISTOL-CITY-COUNCIL is operated by Bristol City Council.

What it's used for

  • The address space carries municipal infrastructure, evidenced by netnames BRISTOL-CC and BRISTOL-CYPS registered to Bristol City Council.
  • The AS announces 2560 IPv4 addresses across 2 prefixes with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal government services, administrative endpoints, and municipal IT systems for the city of Bristol.

Notable

  • Registrants for both announced prefixes align with the AS holder, listing Bristol City Council as the registrant for BRISTOL-CC and BRISTOL-CYPS.
  • The inventory consists of two distinct IPv4 blocks: 193.35.232.0/21 and 195.246.108.0/23, with no IPv6 prefixes announced.

Reputation

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.
