Summary
Sipcom
business it-infrastructure uk
SIPCOM-NET1 is operated by Sipcom (SIP Communications Limited).
What it's used for
- The address space carries corporate IT infrastructure, evidenced by netnames
UK-SIPCOM-20080724,SIPCOMNET, andUK-SIPCOM-20130902, and reverse DNSavuk3epa.sipcom.com. - The AS announces 2560 IPv4 addresses across 9 prefixes and 1 IPv6 prefix, with 74 observed neighbours; this ratio indicates a transit or peering-heavy role rather than a large access network.
- Traffic from this AS consists of web/API endpoints and internal corporate services for Sipcom’s IT infrastructure and cloud consultancy business.
Notable
- Registrants for the 93.187.x.x and 185.34.x.x blocks align with the announcer, listing SIP COMMUNICATIONS LIMITED, Sipcom Admin, and SIPCOM IP Engineering.
- Four /24 prefixes in the 8.0.0.0/8 range are registered to Level 3 Parent, LLC under netname
LVLT-ORG-8-8, indicating leased or historically allocated space. - The inventory includes a mix of UK-allocated space and Level 3-registered blocks, with a single large IPv6 /32 prefix.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 436 networks and 1,769 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.
