Summary
1&1 Versatel (Region West)
isp residential legacy
1&1 Versatel GmbH (VERSATEL-NRW) — a subordinate AS of the German fixed-line operator, described in the registry as servicing the former TROPOLYS Region West, i.e. the North Rhine-Westphalia footprint Versatel absorbed.
What it's used for
- Broadband access for end users in the region. Every sampled address resolves under
versanet.dewith the classic German hex-encoded dynamic naming (iHHHHHHHH.versanet.de, where the eight hex digits encode the IPv4 address itself) — the signature of a dynamically assigned DSL pool. - The RIPE objects agree: the covering block is
VT-CUSTOMER, and the route object on it is literally described asVT-DYNAMICPOOL.
Notable
- Small for an eyeball network at roughly 1,800 addresses across four prefixes, and single-homed to the Versatel backbone. This is a regional access ASN, not the group's main network — 1&1 Versatel's larger enterprise and carrier business rides other ASNs.
versanet.deis a fossil of Versanet, the Bochum-based provider that became part of Versatel; the rDNS zone outlived the brand by many years.
Interesting
- The hex rDNS convention is worth recognising on sight. It costs the operator nothing to generate, tells a support engineer the IP without a lookup, and is a reliable tell for German consumer DSL space across several unrelated ISPs.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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.
