About this network

LOCAL-IX is the AS handle for Niigata Communication Service, a regional internet service provider operating in Japan.

What it's used for

• The AS announces 2048 IPv4 addresses within a single prefix (202.59.144.0/21) and maintains 10 observed neighbours, a ratio consistent with a regional access network rather than a transit provider.

Notable
