SPF Record Check and
Lookup tool

Use SPF Record Lookup, if you want to:

  • Check SPF TXT record published in DNS for the domain
  • Check if SPF record's elements and syntax correspond to SPF' specification (RFC7208)
  • Check published SPF record's tree hierarchy of DNS lookups
  • Check all IPs and IP ranges included in SPF
  • Check for the presence of multiple SPF records in DNS, which do lead to SPF record’s “permerror” according to SPF’s specification
  • Check SPF record's length for not exceeding 450 octets, which may lead to SPF record validation error (RFC7208, div 3.4)
  • Check SPF record for recursive include which causes "permerror"
  • Check SPF record for not exceeding "2 Void DNS Lookups", which do lead to SPF record validation error (RFC7208, div 4.6.4)
