Not TTBOMK. It does have an API for managing RRs but that is using RFC 2136 and not HTTP. > I currently use zonefiles to store DNS data > and have been planning to switch to an API to add/remove records.

Or you could just use the RFC 2136 update protocol directly. Or you could use CLI tools supplied with BIND even, such as "nsupdate" that can do updates. If you really want an HTTP API, I guess you could start doing searches for "RFC2136 HTTP" and see if anyone has implemented such a thing. Maybe https://github.com/frillip/noip-rfc2136 does what you want. Perhaps there are others. I will leave that search as an exercise for the reader. Or you could even write your own. I have a faint recollection of writing such a thing as a CGI script in the past. It should not be terribly difficult. Yeah. I found it: #!/bin/bash key_name="put your key name here" args_string=${REQUEST_URI##*\?} eval "${args_string//\&/ }" # undo url encoding pass=${pass//\%2F/\/} pass=${pass//\%3D/=} cat <<EOF >/tmp/kfile.key $key_name IN KEY 512 3 157 $pass EOF cat <<EOF >/tmp/kfile.private Private-key-format: v1.2 Algorithm: 157 (HMAC_MD5) Key: $pass EOF oldip=$(host $host | sed -e 's/.* has address //') echo "server localhost update delete $host 0 IN A $oldip update add $host 60 IN A $REMOTE_ADDR send" | nsupdate -d -k /tmp/kfile >&2 rm -f /tmp/kfile.* echo "Content-type: text/html good $REMOTE_ADDR" But most likely you will want to use that GitHub project I pointed out above rather than my Q&D hack above. Above is just to illustrate how basic and simple it could be. Cheers, b.
