What's Changed - Highlights

Couple highlights in this release compared to v2.0.5.

  • Added --per-name-ns-rate-limit and --per-ip-ns-rate-limit to enable rate limiting queries sent to nameservers per-second for nameservers on a per name (ace.ns.cloudflare.com) or per NS IP (108.162.195.65) basis
  • Added a --all-nameservers-all-ips mode which acts like --all-nameservers, but in addition to querying every NS at each level, will query all listed IPs for that nameserver. So if emma.ns.cloudflare.com has 3x A and 3x AAAA records, we'll query all of them if this is true. If false, we'll query only 1 per NS.
  • Fixes a bug where in TCP mode with reusing sockets, a timed out lookup could poison the connection causing all subsequent lookups to fail (#605)
  • Fixes a panic where if a name has nameservers that resolve to a local IP (can happen with a parked domain, snowplowingandremoval.com currently has this where its nameservers resolve to 127.0.0.1), we don't panic.

Along with several other small improvements and updates to dependencies. As always, please don't hesitate to open an issue if you notice any problems!
