host your subdomain on your own ?

[lejeczek]

Hi guys.

I'm looking to setup my subdomin in-house and I'm hoping for 
some wise advises from experts, it's my first foray into 
this thus go easy on me please.

zone.top - is hosted by a public registrar
priv.zone.top - I want to delegate to my own bind
I'd hope for some generic recipe and pointer to docs, thanks.

Now what I think might be the tricky part though I get that 
an expert might say - trivial.
I am thinking of 'views' or split-horizon or whatever other 
nomenclature applies, though I hear that that/those are 
discouraged by experts?
Or! might that above be unnecessary(?) if, it's possible and 
allowed that such public, mine bind will resolve to IPs 
which are 'private' - all that so my 'priv.zone.top' will 
resolve to whole www but resources of the zone/domain will 
be available, as they are, only in/via private networks.

Does that make sense?
many thanks for all the help. L
