[6bone] ip6.int or ip6.arpa or BOTH?

[todd@FRIES.NET (Todd T. Fries)]

You want ip6.arpa because at some point in the future ip6.int is going away and
ip6.arpa will be active (in reverse order, though).

Something very basic like:

  sed 's/ip6.int/ip6.arpa/g' zone.ip6.int > zone.ip6.arpa

Should work fine.

Probably not for everyone, but here is my solution:

 http://todd.fries.net/dns/fries/

Files of interest:

	Makefile (generate output, verify, update)
	*.m4     (m4 source files)
	ip6.inc.m4 (contains my reverse subnets and EUID's)
        3ffe:b00:4004.arpa.m4 (ip6.arpa specifics)
        3ffe:b00:4004.int.m4  (ip6.int specifics)

General concept:

	I use m4 to expand the addresses of all my euid's
	across all my subnets when generating both ip6.int
	and ip6.arpa zones.  (yes, it generates not small
	zones, but I got tired of laptops and other devices
	that shift subnets having to update dns for each shift).

I know that freenet6 (aka viagenie) where I have my tunnel does
not delegate ip6.arpa yet, but I am ready for when they do!

Most likely some of you will not be happy with my choice to
do this:

todd:27$ host 3ffe:b00:4004::1
1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.4.0.0.4.0.0.b.0.e.f.f.3.ip6.int is an alias for 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.4.0.0.4.0.0.b.0.e.f.f.3.pt.fries.net.
1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.4.0.0.4.0.0.b.0.e.f.f.3.pt.fries.net domain name pointer shadow.fries.net.
todd:28$

But it ends up allowing forward and reverse in the same zone, which I
like for my own reasons (forced consistency among them).

| That sure looks like an IPv4 in-addr.arpa zone to me.

| zone "0.f.4.0.1.0.0.2.ip6.int" {
|         type master;
|         file "ipv6/0.f.4.0.1.0.0.2.ip6.int";

|         type master;
|         file "ipv6/0.f.4.0.1.0.0.2.ip6.arpa";
| };
| 
| 
|
