title: DNS Discovery
|
||
|
|

|

|

|
|
Built upon the foundation of [EIP-1459: Node Discovery via DNS](https://eips.ethereum.org/EIPS/eip-1459), DNS Discovery allows the retrieval of an `ENR` tree from the `TXT` field of a domain name. This innovative approach enables the storage of essential node connection details, including IP, port, and multiaddr, using the standardized [ENR format](https://rfc.vac.dev/spec/31/).

|
|
||
|
|
This bootstrapping method allows anyone to register and publish a domain name for the network, promoting increased decentralization.
|
||
|
|
|
||
|
|
#### Pros
|
||
|
|
|
||
|
|
- Low latency, low resource requirements.
|
||
|
|
- Easy bootstrap list updates by modifying the domain name, eliminating the need for code changes.
|
||
|
|
- Ability to reference a larger list of nodes by including other domain names in the code or ENR tree.
|
||
|
|
|
||
|
|
#### Cons
|
||
|
|
|
||
|
|
- Vulnerable to censorship: Domain names can be blocked or restricted.
|
||
|
|
- Limited scalability: The listed nodes are at risk of being overwhelmed by receiving all queries. Also, operators must provide their `ENR` to the domain owner for listing.
