dnsvi - edit dynamic DNS zones in vi

dnsvi is a frontend for nsupdate. Given a DNS zone name, it uses dig -t AXFR to get all the records in a zone. It then spawns your favorite editor, and upon completion, builds a list of "update add" and "update delete" statements to feed to nsupdate.

Usage:

./dnsvi [-igl] [-k keyfile] [-p port] [@nameserver] <zone>

Dependencies:

• perl
• Sort::Naturally (Debian: libsort-naturally-perl)
• dig, nsupdate (Debian: dnsutils)
• some $EDITOR (Default: sensible-editor)

If you are updating a punycode domain and you are using bind9 >= 9.14.0, you need to specify -i to be able to update the zone, otherwise there will be a mix of punycode and non-punycode domains which nsupdate will refuse.
