Summary
Maximilian Baehring
vpn residential individual
AS21158 is operated by Maximilian Baehring.
What it's used for
- The address space carries VPN services, evidenced by the reverse DNS record
frankfurt-pptpvpn.msd.dynip.namefor 193.109.132.128. - The AS announces 512 IPv4 addresses within a single /23 prefix and 1 IPv6 prefix, while maintaining 6 observed neighbours; this ratio suggests a small-scale access or service network rather than a transit provider.
Notable
- The RDAP registrant for the announced prefix 193.109.132.0/23 is Maximilian Baehring, which aligns directly with the AS holder name.
- The inventory consists of a single contiguous IPv4 block and one IPv6 /48, indicating a compact, self-contained address estate.

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.
