flatten_spf
shallowai.intodns/scanner · Verify this server
Read-only SPF flattening for a domain. Resolves the full include/a/mx/redirect graph to literal ip4/ip6 addresses and returns a single flattened SPF record that fits under the RFC-7208 10-lookup limit, plus lookup counts before/after, IP count, record length, whether it must be split across multiple records, and a maintenance warning. Use when a domain hits 'too many DNS lookups' (PermError) and removing unused includes is not enough; run check_spf first to see the lookup graph and whether flattening is actually needed. Flattened records are high-maintenance — they break when a provider rotates IPs — so treat the output as a last resort to re-verify periodically. No auth, no side effects.
