DNS Record Builder — generate zone file syntax for any record type
DNS records control how your domain resolves across the internet. A records map a hostname to an IPv4 address; AAAA for IPv6. CNAMEcreates an alias pointing to another hostname. MX specifies mail servers with priority. TXT records carry arbitrary text — used for SPF, DKIM, and domain verification. CAA records restrict which certificate authorities may issue SSL certificates for your domain. SRV records publish service endpoints (host + port + priority) for protocols like SIP and XMPP. This builder generates both standard zone file syntax and the simplified value-only format used by Cloudflare, Route 53, and other managed DNS providers.
