DNS Record Builder
Generate valid DNS zone record lines for common record types.
DNS Record Builder drafts correctly formatted zone records for A, AAAA, CNAME, MX, TXT, and related DNS entries. DNS maps human-readable names to values such as IP addresses, mail exchangers, verification strings, and aliases. An A record points a name to an IPv4 address, AAAA points to IPv6, CNAME aliases one hostname to another, MX declares mail servers with priorities, and TXT stores arbitrary text used for verification, SPF, DKIM, and other policies. TTL controls how long resolvers may cache a record before checking again. This tool helps reduce syntax mistakes before copying records into a DNS provider, but production changes should still respect provider rules, zone ownership, and propagation timing.
