.ne.jp - Japanese Network Service Domain

.ne.jp is a second-level domain under Japan's country-code top-level domain (.jp), designated specifically for network service providers. It is managed by Japan Registry Services Co., Ltd. (JPRS), the official registry for all .jp domains since 2002.

Purpose and Usage

The .ne.jp domain is reserved for organizations providing network-related services in Japan, including:

  • Internet Service Providers (ISPs)
  • Telecommunications companies
  • Network infrastructure providers
  • Online service platforms

This domain type has a "Reserved" status, meaning registrations are restricted to qualifying network service entities rather than being openly available to the general public.

DNS Infrastructure

The domain operates on Japan's authoritative DNS infrastructure:

Record TypeDetails
Nameserversa.dns.jp through h.dns.jp (8 servers)
Primary SOAz.dns.jp
DNSSECSigned with validated chain of trust from root
Authoritative IP203.119.40.1

History

The .jp ccTLD was delegated on August 5, 1986, making it one of the earliest country-code domains. The ne.jp second-level domain was established as part of Japan's structured domain hierarchy to organize registrations by purpose (similar to co.jp for companies, or.jp for organizations, and ac.jp for academic institutions).
