Summary
Sascha Lenz
hosting business germany
The AS handle SLZ-AS is held by Sascha Lenz.
What it's used for
- The address space carries a mix of hosting infrastructure and leased capacity, evidenced by the netname
SLZ-NETassociated with "s-lz.net - Hostmasters" and the netnameDE-OK-20191003associated with "BayCIX GmbH; BayCIX - Network Operations". - The AS announces 1536 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining only 1 observed neighbour, a ratio that suggests a small-scale hosting or business network rather than a transit provider.
Notable
- Registrants do not fully agree with the announcer; while the 195.137.210.0/23 prefix is registered to Sascha Lenz, the 91.194.118.0/23 and 91.194.124.0/23 prefixes are registered to BayCIX GmbH.
- The address inventory consists of three /23 blocks in the IPv4 space and a single /40 block in the IPv6 space, all located in Germany.

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
