Unclassified RIPE
Summary
Yuusei
hosting leased uk
The AS handle YUUSEI is held by Yuusei LTD.
What it's used for
- The address space carries netnames of
ipxoandNET-151-242-65-0-24, with registrants listed as Internet Utilities Europe and Asia Limited and Private Customer. - The AS announces 3072 IPv4 addresses across 6 prefixes and 2 IPv6 prefixes, with only 2 observed neighbours, indicating a small-scale hosting or leased space operation rather than a transit provider.
- Traffic from this AS consists of web and API endpoints hosted on leased infrastructure, given the association with Internet Utilities and the lack of residential access indicators.
Notable
- Registrants for the majority of prefixes are Internet Utilities Europe and Asia Limited, while the announcer is Yuusei LTD, suggesting the address space is leased or managed by a third party.
- The address inventory is fragmented across multiple /23 and /24 blocks in the 2.26.0.0/16 and 2.27.0.0/16 ranges, plus a single /24 in 151.242.0.0/16.

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 2026-10-30, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 447 networks and 1,849 prefixes, as published 2026-10-30. 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.
