Well, sorta.

In the mylan.lan zone file you have:

bonsai.mylan.lan    IN    A    192.168.100.1

BIND interprets this as:
bonsai.mylan.lan.mylan.lan.    IN    A    192.168.100.1

because you didn't terminate the name with a "."




In the reverse zone you have:

10            IN    PTR    bonsai.mylan.lan.

shouldn't this be:
1            IN    PTR    bonsai.mylan.lan.

to match the "A" record above in the mylan.lan zone file?
My bad. Ignorance on my part not placing the "." 

You are right, it should be:
 1            IN    PTR    bonsai.mylan.lan.

When I restart named, something makes the change. I don't understand.
