Autonomous system
AS15418 IONOS-ANYCAST IONOS SE
Hosting RIPE
Summary
IONOS / Fasthosts
hosting cloud
An anycast Autonomous System (IONOS-ANYCAST) registered to Fasthosts Internet Limited, a UK hosting brand within the IONOS group (formerly 1&1 IONOS). Used to announce anycast prefixes for IONOS/Fasthosts services.
What it's used for
- Anycast-served infrastructure (e.g. DNS and other globally distributed endpoints) for IONOS and Fasthosts hosting customers.
Notable
- An IP here identifies IONOS/Fasthosts as the host, not the operator of the service on it.
- Small anycast block that upstreams to the wider IONOS network (AS8560 IONOS SE and AS54548 IONOS Cloud); the larger customer hosting sits on those ASNs.
Interesting
- IONOS is one of Europe's largest mass-market web hosts, grown from the German 1&1 business; Fasthosts is its UK-focused brand.

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 1,771 prefixes, as published 2026-10-15. 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.
