IPv64 Logo Free DynDNS with IPv4 and IPv6

Your internet provider changes your IP address, your domain name stays the same. IPv64 updates your DNS records automatically whenever your address changes, so your NAS, your VPN or your home server is always reachable under one name. Free of charge and compatible with the DynDNS2 protocol used by almost every router.

Free to use

These IPv64.net DynDNS services are free of charge. In the free variant up to 3 DynDNS domains are fully usable.
19 domain endings

Choose your name under 19 domains such as ipv64.net, ipv64.de, home64.de, nas64.de or vpn64.de.

Own Domains

Bring your own domain, point its nameservers to IPv64.net and manage all DNS records here, including DynDNS updates. We are not a registrar.
IPv4 & IPv6

A and AAAA records are updated together or separately. IPv6 prefixes are supported, and connections behind DS-Lite or CG-NAT can ignore the shared IPv4 address.
Easy integration

FRITZ!Box, Speedport, UniFi, MikroTik, OPNsense, Synology or a simple cron job on Linux. Ready-made update URLs are available for every device.

DDoS Protection

IPv64.net DNS servers are connected to multiple Load-balancers. These in turn distribute the DNS requests and have a sophisticated DDoS protection.
Load-Balancing

The IPv64.net load balancers ensure a clean distribution of DNS requests, as well as requests towards the update & API interface.
Let's Encrypt

IPv64.net is fully integrated with ACME.sh and Certbot. Issuing valid certificates is easily possible with the DNS Challenge and IPv64.

DNS Failover

If one of the IPv64 DNS servers fails, automatic measures take effect immediately and initiate a failover.
SSL encryption

All communication channels are fully end-to-end SSL encrypted.
