Summary
Stadtwerke Luebeck Digital
isp regional fiber germany
The AS handle SWHL-AS is operated by Stadtwerke Luebeck Digital GmbH.
What it's used for
- The address space carries fiber-to-the-home services, as indicated by reverse DNS entries such as
254-111-249-149.net.glasfaser.swhl.deand254-23-233-85.net.glasfaser.swhl.de. - The network announces 24,576 IPv4 addresses across 2 prefixes and 15 IPv6 prefixes, while maintaining 132 observed neighbours; this high neighbour-to-address ratio suggests a regional access provider with significant peering relationships.
Notable
- Registrants for both announced IPv4 prefixes (
DE-SWLDIGITAL-19930901andDE-SWLDIGITAL-20050420) are listed as Stadtwerke Luebeck Digital GmbH, aligning with the AS holder. - The operator is also known by the names TRAVEKOM and TraveNetz, reflecting its history as a regional telecommunications provider in Lübeck.
- The inventory consists of two large IPv4 blocks and a fragmented set of IPv6 prefixes, typical of a regional ISP managing both legacy and modern address space.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
