A Simple Webinterface to manage all your DynDNS Domains!
DynDNS
Dynamic DNS (DynDNS) is a technique that lets a fixed hostname always resolve to the current public IP address of a device whose IP changes frequently.
Example:
You own the domain myhome.dyndns.org.
When your ISP assigns a new IP to your home network, the DNS record for myhome.dyndns.org is updated automatically, so anyone can reach your home services by simply typing that hostname, regardless of the actual IP at the moment.
DNS record types involved
| Record | What it stores | Typical use in DynDNS |
|---|---|---|
| A | IPv4 address | The hostname’s IPv4 mapping. Updated whenever the IPv4 address changes. |
| AAAA | IPv6 address | The hostname’s IPv6 mapping. Updated when the IPv6 address changes. |
| DynDNS record | A special DNS update mechanism (often a TXT or SRV entry used by the provider) | Signals to the DNS provider that the hostname should be refreshed automatically; the provider’s API updates the A/AAAA records on your behalf. |
