amateur radio ham germany

The AS handle SCHRAMM is held by Tobias Schramm.

What it's used for

  • The space carries amateur radio traffic, evidenced by the netname AMPRNET and registrant Amateur Radio Digital Communications associated with the announced prefix.
  • The inventory consists of 256 IPv4 addresses and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small-scale access or hobbyist network rather than a transit provider.
  • Traffic from this AS is amateur radio digital communications, consistent with the holder's registration under the Amateur Radio Digital Communications organization.

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
