Is anyone out there using $GENERATE to create blocks of AAAA and PTR records for IPv6? Particularly PTR records?
It seems easy enough to create AAAA records automatically:
$ORIGIN infracaninophile.co.uk.
$GENERATE 0-255 2001-8b0-151-1-240-0-1234-${0,0,x} AAAA
2001:8b0:151:1:240:0:1234:${0,0,x}
but how to create the corresponding PTR records? Since the labels for
.ip6.arpa records are single hex digits, then I'd have to have 16 $GENERATE
lines to create 256 PTR records like so:
$ORIGIN 1.0.0.0.1.5.1.0.0.b.8.0.1.0.0.2.ip6.arpa.
$GENERATE 0-15 ${0,0,x}.0.0.0.4.3.2.1.0.0.0.0.0.4.2.0 PTR
2001-8b0-151-1-240-0-1234-${0,0,x}.infracaninophile.co.uk.
$GENERATE 16-31 ${0,0,x}.1.0.0.4.3.2.1.0.0.0.0.0.4.2.0 PTR
2001-8b0-151-1-240-0-1234-${0,0,x}.infracaninophile.co.uk.
$GENERATE 32-47 ${0,0,x}.2.0.0.4.3.2.1.0.0.0.0.0.4.2.0 PTR
2001-8b0-151-1-240-0-1234-${0,0,x}.infracaninophile.co.uk.
etc...
which seems to pretty much obviate the point of using $GENERATE in the
first place. Other than writing a few scripts to generate the list
records directly are there any alternatives?
It would be handy if there was a format code eg 'P' that produced
reverse order hex digits separated by '.' -- so eg ${0,4,P} would
expand to something like
0.0.0.0
1.0.0.0
2.0.0.0
...
d.f.0.0
e.f.0.0
f.f.0.0
for the example above.
Cheers,
Matthew
