Summary

Surfplanet

Germany · AI-generated

hosting datacenter business

SURFPLANET-AS is operated by Surfplanet GmbH, a data center provider based in Cologne, Germany.

What it's used for

  • The address space carries hosting and data center infrastructure, evidenced by the reverse DNS record ns2.germanvps.com and the netname DALASON-DC-CGN associated with the prefix 45.15.101.0/24.
  • The AS announces 19,200 IPv4 addresses across 6 prefixes and 2 IPv6 prefixes, while maintaining only 4 observed neighbours. This high address-to-neighbour ratio indicates a hosting or access network rather than a transit provider.

Notable

  • Registrants for the majority of prefixes align with the announcer, specifically Surfplanet GmbH for 85.88.0.0/19, 78.111.64.0/20, 81.20.128.0/20, and 46.235.24.0/21.
  • The prefix 217.117.110.0/23 is registered to uniserve GmbH with the netname DE-UNISERVE-20010208, suggesting a distinct ownership or historical lease separate from the primary Surfplanet inventory.
  • The inventory consists of a mix of /19, /20, /21, /23, and /24 blocks, with the largest allocation being 85.88.0.0/19.

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 1,782 prefixes, as published 2026-10-16. 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.
