Summary
Portfast
hosting isp legacy
PORTFAST is Portfast Ltd, a small British hosting and network provider registered in Sheffield. It sells KVM virtual machines, colocation and IP transit, and runs its own routing and address space.
What it's used for
- Virtual-machine hosting (
portfast.netKVM VPS with native IPv6), colocation and transit for a modest customer base. - About 6,600 IPv4 addresses across a
188.246.192.0/20allocation and two provider-independent blocks, plus an IPv6 /29 and a /48. Three upstream neighbours.
Notable
- The rDNS that exists is Portfast's own backbone — router interfaces named
gi0-0-1.rt0.SITE.portfast.netand hosts named after Greek letters (eth0.eta.portfast.net). Customer VM space is largely undelegated, which is normal for a VPS provider. - Every allocation is self-registered under Portfast's own maintainer, and the one block registered to a third party (
130.193.30.0/24, Roebuck Group Ltd) is a straightforward customer route rather than brokered space.
Interesting
- The AS number is early-1990s vintage but RIPE records the current holder's registration in 2009, and its oldest allocation dates from 2011. This is a reissued number, not an early-internet allocation — the company simply inherited a low one.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
