Summary
IONOS (1&1)
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&1is 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.
