* github.com/miekg/dns * Greatly simplify the logic for handling serial numbers. Related code was all over the place. Now it is abstracted into one testable method makeSoa. This simplifies code in many other places. * Update docs/_providers/bind.md: Edit old text. Add SOA description. * SOA records are now treated like any other record internally. You still can't specify them in dnsconfig.js, but that's by design. * The URL for issue 491 was wrong in many places * BIND: Clarify GENERATE_ZONEFILE message

Most providers do not support SOA records. They generate them

dynamically behind the scenes. Providers like BIND (which is

software, not SaaS), must handle SOA records and emulate the dynamic

work that providers do.
