What it's used for
- The address space carries the netname
DE-SCHNEEWEISS-20150126, registered to the operator's business name. - The AS announces 1024 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, isolated network rather than a transit or large access provider.
- Traffic from this AS consists of internal corporate endpoints and system programming services, consistent with the operator's business focus on technical system programming.
Notable

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
