Struct DiscoveryConfig 

pub struct DiscoveryConfig {
    pub pkarr_url: Option<String>,
    pub dns_origin: Option<String>,
    pub peers: Option<HashMap<String, DiscoveryPeer>>,
}

Operator-configurable address-discovery providers (#818 scope 1).

Two mechanisms, selectable by which keys are present and combinable:

• Custom pkarr + DNS (Self::pkarr_url + Self::dns_origin) — publish this node’s signed address record to an operator-run pkarr relay and resolve peers via an operator-run DNS server. Closest to n0’s model; supports dynamic addresses.
• Static peer map (Self::peers) — a MemoryLookup address book supplied directly in config. Fully offline/isolated; addresses must be known ahead of time.

Fields

pkarr_url: Option<String>

pkarr relay URL this node PUBLISHES its signed address record to. Must be paired with Self::dns_origin (a resolver for the same namespace): publishing to a relay nothing resolves from is rejected at config validation. Parse-checked as a URL at resolution.

dns_origin: Option<String>

DNS origin domain this node RESOLVES peer addresses from (TXT queries _iroh.<z32-id>.<dns_origin>). Valid on its own (a resolve-only node that does not publish). Checked non-empty at resolution.

peers: Option<HashMap<String, DiscoveryPeer>>

Static peer address book seeded into a MemoryLookup, keyed by peer NodeId (the canonical 64-char lowercase-hex form iroh emits; validated with the same parser the node uses at bring-up). Composes alongside the pkarr/DNS leg when both are set.
