DNS Lookup
A, AAAA, CNAME, MX, NS, TXT (SPF/DMARC) and SOA records for a domain, with email-authentication checks.
Why it matters
Email from your domain lands in spam without SPF and DMARC; a wrong A record takes the site down. DNS is where many 'the site is broken' calls begin.
What you get
A, AAAA, CNAME, MX, NS, TXT and SOA records, plus checks for SPF, DMARC and mail setup.
