I am still learning, however, I don't think that the browser will need
the DNS resolution for an IP address. The only time that it is used
with an IP address is when the client requires reverse lookup for an
address. Hence, the zone file of type given below.

zone "0.0.168.192.in-addr.arpa" {
type master;
file "file.whatever.IP";
allow-update { none; };
}

I hope this helped your inquiry.
