Summary
Japan Registry Services
registry infrastructure japan
JPRS is operated by Japan Registry Services Co., Ltd., the organization responsible for managing the .jp top-level domain.
What it's used for
- The address space carries internal registry infrastructure, evidenced by reverse DNS entries such as
vl20.ex-gw2202nc.tyo.jprs.co.jpand103.47.2.64.tyo.jprs.co.jp. - With 1024 IPv4 addresses announced across 3 prefixes and only 3 observed neighbours, the network functions as a small, self-contained internal estate rather than a transit or access provider.
Notable
- All registrants for the announced prefixes are listed as Japan Network Information Center (JPNIC), which is consistent with JPRS's role as the .jp registry operator.
- The inventory consists of three IPv4 prefixes and two IPv6 prefixes, all located in Japan, reflecting a tightly scoped operational footprint.

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 1,771 prefixes, as published 2026-10-15. 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.
