Summary

IONOS (1&1)

Global · AI-generated

hosting cloud web

IONOS (IONOS-AS) — a large European web host and cloud provider, the joint network for IONOS, Fasthosts, Arsys, and the former 1&1 brands.

What it's used for

  • Shared web hosting, domains, email, and cloud servers for a very large base of small-business and consumer websites, primarily in Europe.

Notable

  • A mass-market hosting network: an IP here typically fronts many small hosted sites, not a single big service.
  • 1&1 is the well-known legacy brand behind IONOS.

Interesting

  • IONOS is one of Europe's largest web hosts by number of hosted domains, which is why its address space shows up behind a huge variety of small sites.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
