About this network

ISNS1 is operated by ISNS.

What it's used for

• The address space is registered under the netname ISNS-1 with registrant ISNS, indicating a single-tenant corporate or business allocation.
• The AS announces 256 IPv4 addresses within a single /24 prefix (23.129.96.0/24) and maintains 2 observed routing neighbours. This low neighbour count relative to the address block suggests a small-scale access or internal business network rather than a transit provider.

Notable

• The RDAP registrant ISNS matches the AS handle ISNS1 and the netname ISNS-1, confirming consistent ownership of the address space.
• The inventory consists of a single contiguous IPv4 block with no announced IPv6 prefixes, representing a minimal and focused address estate.
