Summary
Entanet (CityFibre)
isp wholesale legacy
Entanet (ENTANET, registered to Cityfibre Limited) is a long-running UK wholesale internet provider. It does not sell to end users directly; it supplies broadband, leased lines and voice to a channel of reseller ISPs and managed service providers, who brand the service as their own.
What it's used for
- Wholesale broadband and Ethernet circuits delivered through partner ISPs to UK businesses and, via those partners, some home users.
- Hosted voice and connectivity services for the same reseller channel.
Notable
- Almost every address resolves to
IP-WITH-DASHES.static.enta.net, with named business sites mixed in — a channel/wholesale footprint rather than a dynamically addressed consumer eyeball network. - Because the addresses are handed to partner ISPs and their customers, the organisation named on the AS is rarely the organisation actually using a given block.
Interesting
- CityFibre bought Entanet in 2017 to gain a wholesale partner base, and agreed in 2026 to sell the business on to telecoms entrepreneur Tom O'Hagan while keeping Entanet as a wholesale customer of its fibre network. The RIPE handle still reads
ENTANETregardless of who owns it.

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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
