Summary
GRMML Networks
research education ipv6 germany
The AS handle GRMML is held by Hermann Lienstromberg.
What it's used for
- The space carries research and educational traffic, identified by the netname
DE-HERMANNLIENSTROMBERG-20200129and the registrant Hermann Lienstromberg. - The AS announces 256 IPv4 addresses and 21 IPv6 prefixes while maintaining 50 observed neighbours, a ratio that indicates a transit or peering-heavy role rather than a large access network.
- Traffic from this AS consists of academic and research endpoints associated with the GRMML Networks project, which focuses on network measurement and experimentation.
Notable
- The RDAP registrant for the announced IPv4 prefix matches the AS holder, confirming direct ownership of the address space.
- The address inventory is dominated by IPv6, with 21 prefixes announced compared to a single IPv4 /24, reflecting a modern, IPv6-first research infrastructure.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
