Unclassified RIPE
Summary
Zone Broadband
cable dsl isp uk
ZONEBROADBAND is operated by Zone Telecommunications Ltd, trading as Zone Broadband.
What it's used for
- The address space carries netnames
UK-OFFICENET-20191007registered to OfficeNet Systems Limited, indicating a corporate or managed network estate rather than direct consumer access. - The AS announces 768 IPv4 addresses across 2 prefixes with 1 observed neighbour, a ratio consistent with a small-scale access or business network rather than a transit provider.
Notable
- The registrant for both announced prefixes is OfficeNet Systems Limited, which differs from the AS holder Zone Telecommunications Ltd, suggesting a lease or partnership arrangement.
- Secondary sources indicate Zone Telecommunications Ltd entered administration, with its trading name Zone Broadband and business nature described as wired telecommunications activities.
- The inventory consists of two contiguous IPv4 prefixes (193.26.212.0/23 and 193.26.211.0/24) with no IPv6 announcements.

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 1,784 prefixes, as published 2026-10-19. 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.
