 STYLE: Replace deprecated given/when with if/elsif 
Completes the smartmatch removal from #8 — the previous fix
(e661031) missed the IDN unicode block in parse() that converts
CNAME/NS/PTR/MX/SRV/TXT data via domain_to_ascii / esc_txt.

Silences "given is deprecated" / "when is deprecated" warnings on
recent Perls. CNAME/NS/PTR share a single branch since their bodies
are identical.

DNSvi

If you do not have access to the zone files but need to modify a given DNS zone, DNSvi is your friend.

It downloads the zone via AXFR, removes RRSIG and NSEC records, lets you edit the zone content using your favourite editor and sends the changes back via the NSUPDATE protocol.

Unfortunately there is an alternative project using the same name. I do not know anything about this, whether it provides matching functionality or does something completely different.

DNSvi can modify the zone locally on the DNS server, and even remotely.

Build

DNSvi uses the standard Perl tool chain (Extutils::MakeMaker).

perl Makefile.PL
make all test install

Configuration

Please read the manual page, once DNSvi is installed. Basically you need to:

  • make sure that you're allowed to transfer the zone via AXFR
  • make sure that you can update the zone via nsupdate

If you want to use DNSvi remotely you likely need to create a TSIG key and configure your DNS server accordingly.

Usage

Just start DNSvi locally on the DNS server:

dnsvi -l example.com

Or if you configured remote access:

dnsvi example.com
