Most of the time you can use a ĐNS library to do what you need. If for whatever reason, you need to interact with ĐNS directly, details for the currently supported deployments are detailed here.
The DNS registry is deployed at 0x834C46666c1dE7367B252682B9ABAb458DD333bf on mainnet, and 0x08850859CE6B62A39918c8B806AfbE3442fE7b0b on testnet.
On mainnet, the following registrars are deployed:
- .doge, using the .doge Permanent registrar.
To find out the contract address of each tld, check the "controller" address of the tld (eg: https://app.dogedomains.wf/name/doge for .doge
In addition, the test networks also have a deployment of the .doge registrar for testing purposes.
For other contract addresses such as root, multisig, controller, public resolver, and so on, you can see their address under https://app.dogedomains.wf/name/dns.doge/subdomains
