Unclassified RIPE
Summary
Securus Communications
business security connectivity
The AS handle SECURUS is held by Securus Communications Ltd.
What it's used for
- The address space carries managed cybersecurity and resilient connectivity services, evidenced by the reverse DNS record
port-254-125.securuscomms.co.ukand netnamesUK-SCL-20120730,UK-SCL-20170911, andUK-SCL-20170918. - The network announces 4096 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining 81 observed neighbours; this ratio of limited address space against a high neighbour count indicates a transit or interconnection role rather than a large-scale access network.
- Traffic from this AS consists of managed cyber security infrastructure, firewalls, threat detection systems, and private cloud connectivity for business clients requiring resilient multi-site networks.
Notable
- All RDAP registrants for the announced prefixes are listed as Securus Communications Ltd., agreeing with the AS holder.
- The address inventory is composed of three distinct IPv4 blocks: 5.159.120.0/21, 185.220.88.0/22, and 185.221.144.0/22, alongside a single IPv6 prefix 2a07:c9c0::/29.

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.
