Overview

Package dnsx is the DNS interface every lookup in lfr goes through, so tests run against a fake zone and production gets timeouts and an optional fixed resolver.

Types

type Resolver interface {
	LookupTXT(ctx context.Context, name string) ([]string, error)
	LookupMX(ctx context.Context, name string) ([]*net.MX, error)

	LookupAddr(ctx context.Context, addr string) ([]string, error)
