Unclassified RIPE Enterprise
Summary
link-lab GbR Schmidt Waehlisch
business enterprise germany
LINKLAB-AS is operated by link-lab GbR Schmidt Waehlisch.
What it's used for
- The address space carries enterprise traffic, with one prefix registered under the netname
NET-UM-BMBF-01and another underDE-UNBELIEVABLE-20180514. - The AS announces 768 IPv4 addresses across 2 prefixes and 2 IPv6 prefixes, while maintaining 13 observed neighbours; this ratio of limited address space against a moderate number of peers indicates a business or enterprise network rather than a large-scale access provider.
- As an enterprise entity, the traffic consists of internal corporate communications and web/API endpoints for the organization's operations.
Notable
- Registrants do not fully align with the announcer; the 194.13.70.0/23 block is registered to Orange Business Digital Germany GmbH, while the 91.216.216.0/24 block is registered to link-lab GbR Schmidt Waehlisch.
- The inventory is small and finely subdivided, consistent with an internal corporate estate rather than a broad residential or hosting footprint.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
