Summary
Giga5
residential isp cable dsl
SWNNMS is operated by SWN Stadtwerke Neumünster GmbH, a municipal utility in Neumünster, Germany, which provides consumer internet services under the brand Giga5.
What it's used for
- The address space carries residential broadband traffic, as indicated by the PeeringDB classification of "Cable/DSL/ISP" and the operator's public identity as a regional ISP.
- The AS announces 146,432 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, while maintaining 134 observed routing neighbours. This ratio of moderate address space to a high number of peers suggests a regional access network that aggregates traffic from multiple upstream providers rather than a large-scale transit provider.
- Traffic from this AS consists of subscriber eyeballs for residential cable and DSL connections in the Neumünster region, serving the local population with internet access services.
Notable
- Registrants for the majority of prefixes (89.56.0.0/15, 194.97.96.0/19, and 185.12.88.0/22) are listed as SWN Stadtwerke Neumünster GmbH, aligning with the AS holder. The prefixes 62.197.0.0/20 and 62.197.16.0/21 are registered under the netname NORTHCON-NET-1, indicating leased or historically allocated space.
- The operator is a subsidiary of the municipal utility SWN, which has been active in the region for over 125 years and is recognized as a leading employer in the area.
- The inventory includes a mix of larger blocks (such as the /15) and smaller subdivisions, typical of a regional ISP managing both legacy and newer address allocations.

Reputation
Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
