pub const MAGIC_DNS: &str = "sslip.io";Expand description
The magic-DNS provider used when there is no domain.
sslip.io rather than nip.io: since 2025 both are operated by the
same maintainer and share one Let’s Encrypt rate-limit pool, so there
is no availability to be gained by preferring one, and sslip.io is
the one whose own documentation demonstrates the issuance path. That
shared pool is also why --public-name exists — the limit has been
exhausted before, and a rate-limited third party must never be the
only way to stand a node up.
