Summary
SERVER-G Group
non-profit chess japan small
SERVER-G is operated by SERVER-G Group.
What it's used for
- The space carries infrastructure for the Free Internet Chess Server (FICS), a volunteer-run online chess platform, as indicated by the operator's non-profit status and web presence.
- The AS announces 256 IPv4 addresses and 9 IPv6 prefixes, with 6 observed neighbours, indicating a small-scale service network rather than a transit or large access provider.
- Traffic from this AS consists of web and API endpoints for the chess platform, supporting user connections and game data exchange.
Notable
- The registrant for the IPv4 block is Japan Network Information Center (JPNIC), which is consistent with the Japanese allocation of the address space.
- The address inventory is compact, consisting of a single /24 IPv4 block and multiple /48 IPv6 prefixes, typical for a specialized service provider.

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.
