Dns Record Generator

Produces a BIND/zone-file style DNS record line from a form. Supports seven record types: A, AAAA, CNAME, MX, TXT, SRV, and CAA. The output updates live in a read-only textarea as you change fields, and can be copied to the clipboard.

1. Choose Record Type (A, AAAA, CNAME, MX, TXT, SRV, or CAA). 2. Set the common fields: Domain (defaults to example.com) and TTL (defaults to 3600; the TTL column is omitted from output when it equals 3600). 3. Fill the type-specific fields that appear (IPv4/IPv6 address, CNAME target, MX priority + server, TXT value, SRV priority/weight/port/target, or CAA flag/tag/value). 4. Copy the generated record from the output box.

Each line follows `<domain>. IN[ <ttl>] <type> <values>`. Examples the tool produces: A -> `example.com. IN A 192.168.1.1`; AAAA -> `example.com. IN AAAA 2001:db8::1`; CNAME -> `example.com. IN CNAME example.com.`; MX -> `example.com. IN MX 10 mail.example.com.`; TXT -> `example.com. IN TXT "v=spf1 ..."`; SRV -> `example.com. IN SRV 10 60 5060 sip.example.com.`; CAA -> `example.com. IN CAA 0 issue "letsencrypt.org"`. CAA flag is 0 (Non-critical) or 128 (Critical); CAA tag is issue, issuewild, or iodef.
