Summary
Plus.line AG
hosting colo legacy
Plus.line AG is a Frankfurt hosting and colocation provider.
What it's used for
- Hosting and connectivity from its own address space, 40,440 IPv4 addresses across 39 announced prefixes.
Notable
- 141 observed BGP neighbours against a network of that size. Frankfurt is where a disproportionate share of European interconnection happens, and a provider based there peers far more widely than its address count would suggest.
- The netnames date the space:
DE-PLUSLINE-990303was registered on the 3rd of March 1999,DE-PLUSLINE-20031204in December 2003. - 41 IPv6 prefixes are announced — more IPv6 prefixes than IPv4 ones, which almost no network can say.
Interesting
- Those 41 IPv6 prefixes all sit inside a single
2a02:2e0::/32allocation, and they nest: a/39, then a/40,/41,/42,/43,/45,/46,/47and/48, each tucked inside the last. Announcing a/32as dozens of nested pieces is the IPv6 version of a habit operators picked up in IPv4, where splitting a block was how you steered traffic between upstreams. IPv6 was meant to make that unnecessary, having handed everyone enough space to never need to subdivide for routing reasons — and here it is anyway.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
