Summary
man-da.de (MANDA, Darmstadt)
education research legacy
MANDA — man-da.de GmbH, the operating company for MANDA, the Metropolitan Area Network Darmstadt. It is owned in equal parts by TU Darmstadt and Hochschule Darmstadt and serves the scientific community of Darmstadt and southern Hesse.
What it's used for
- Regional research and education networking. The AS originates the university blocks directly:
130.83.0.0/16is TU Darmstadt (rDNS such asHOST.ikp.physik.tu-darmstadt.de) and141.100.0.0/16is Hochschule Darmstadt;82.195.64.0/19carries further Hessian institutions.
Notable
- An NREN-adjacent regional network, not a commercial carrier despite the "GmbH" — the shareholders are the two universities it serves.
- The very large neighbour count comes from man-da.de peering openly at Frankfurt's exchanges, which sits it in the middle of one of the densest interconnection markets in the world for a network of its size.
Interesting
- The
130.83.0.0/16block is a legacy Class B held by TU Darmstadt from the early days of German academic networking; MANDA announces it on the university's behalf.

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.
