About this network

SUISEI-AS-AP is held by Shuji Ito.

What it's used for

• The space carries academic and research traffic, as indicated by the PeeringDB classification of "Educational/Research" and the website suiseinetwork.sccsn.jp.
• The AS announces 256 IPv4 addresses and 2 IPv6 prefixes, with 5 observed neighbours; this low neighbour count relative to the address inventory suggests a small, dedicated research network rather than a transit provider.
• Traffic from this AS consists of web endpoints and research infrastructure associated with the Suisei Network project.

Notable

• The registrant for the announced IPv4 prefix 185.155.75.0/24 is 17016905 CANADA CORP., which differs from the AS holder Shuji Ito, indicating the address space is leased or allocated through a Canadian entity.
• The address inventory is small, consisting of a single /24 IPv4 block and two IPv6 prefixes, consistent with a niche academic network.
