Module dns 

FIPS DNS Responder

Resolves .fips queries to FipsAddress IPv6 addresses. Two resolution paths are supported:

1. Hostname: <hostname>.fips — looked up in the HostMap to get an npub, then resolved to IPv6.
2. Direct npub: <npub>.fips — pure computation from public key.

As a side effect, resolved identities are sent to the Node for identity cache population, enabling subsequent TUN packet routing.
