Summary

SERVER-G Group

Japan · AI-generated

educational research amateur radio

TEAMFELNULL is operated by SERVER-G Group.

What it's used for

  • The address space carries amateur radio digital communications, evidenced by the netname AMPRNET and registrant Amateur Radio Digital Communications for the announced IPv4 block.
  • The AS announces 256 IPv4 addresses and 3 IPv6 prefixes, with only 2 observed routing neighbours, indicating a small-scale research or educational network rather than a transit provider.
  • Traffic from this AS consists of experimental and educational data related to amateur radio digital modes and associated development projects.

Notable

  • The RDAP registrant Amateur Radio Digital Communications differs from the AS holder SERVER-G Group, reflecting the specific purpose of the allocated address space.
  • The address inventory is minimal, consisting of a single /24 IPv4 prefix and three IPv6 prefixes, all located in Japan.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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 1,781 prefixes, as published 2026-10-16. 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.
