IPv64.net documentation

Everything you need to set up and use IPv64.net: free DynDNS for IPv4 and IPv6 with update URL and DNS failover, health checks, CDN64 without port forwarding, the IP blocklists and the Cloud Router with VPN. Every page has the navigation on the left, the jump marks on the right – and the search at the top left (key /).

Quick start: DynDNS in three steps

  1. Create an account
    Sign up for free at ipv64.net/account. What the account classes differ in is explained under Account & limits.
  2. Create a domain
    Create your domain under DynDNS, e.g. myhomenet.ipv64.net. Details: DynDNS domains.
  3. Update your IP automatically
    Enter the update URL in your router or a script. Guides for many devices are under Routers & devices, the technology behind it under Update URL & protocol.
