Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of ipaddr.js, so you can see the experience inside your AI.

It does not authenticate your account with ipaddr.js. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions ipaddr.js owners ask.

  • 01

    How does it know if an IP is private or public?

    It follows the IANA reserved ranges defined in RFC 5735 (IPv4) and RFC 4291 (IPv6). 10.x.x.x, 172.16-31.x.x, and 192.168.x.x are classified as 'private'. 127.x.x.x as 'loopback'. Everything else as 'unicast' (public).

  • 02

    Can I check if an IP belongs to a specific CIDR range?

    Yes. Pass the CIDR notation like '10.0.0.0/8' and the engine returns the network address, prefix length, and address kind. Parse both the IP and the CIDR to compare.

  • 03

    Does it work with IPv6 addresses?

    Yes. Full IPv6 support including compressed notation (::1), IPv4-mapped (::ffff:192.168.1.1), and all RFC 4291 scoped addresses.
