DNS bind9 not working with localhost?

Question

Domain Name System

Raised a domain controller on Ubuntu and replicated the database from DC Windows Server. Everything seemed to work, but bind9 does not want to define localhost in any way.

host -t A localhost 127.0.0.1

Using domain server:
Name: 127.0.0.1
Address: 127.0.0.1#53
Aliases:

Host localhost not found: 2(SERVFAIL)

host -t PTR 127.0.0.1 127.0.0.1

Using domain server:
Name: 127.0.0.1
Address: 127.0.0.1#53
Aliases:

Host 1.0.0.127.in-addr.arpa not found: 2(SERVFAIL)

As a result, the database was not fully replicated.

What's the matter and why is the DNS server not working as expected? How to configure resolving?
