## DNS discovery for Bor peering

ENR trees for DNS-based peer discovery:

* **Mainnet** - `enrtree://AKUEZKN7PSKVNR65FZDHECMKOJQSGPARGTPPBI7WS2VUL4EGR6XPC@pos.polygon-peers.io`
* **Amoy Testnet** - `enrtree://AKUEZKN7PSKVNR65FZDHECMKOJQSGPARGTPPBI7WS2VUL4EGR6XPC@amoy.polygon-peers.io`

### DNS discovery configuration

Set the following values in `config.toml` to use DNS discovery:

| Section           | Parameter      | Mainnet            | Amoy Testnet       |
| ----------------- | -------------- | ------------------ | ------------------ |
| `[p2p]`           | `maxpeers`     | 2000               | 500                |
| `[p2p]`           | `maxpendpeers` | 500                | 100                |
| `[p2p.discovery]` | DNS entry      | See ENR tree above | See ENR tree above |

Adding the ENR tree under `[p2p.discovery]` enables DNS-based peer discovery. Increasing `maxpeers` and `maxpendpeers` improves peering efficiency but increases bandwidth usage.
