DNS and BIND: Create a Forward Zone File

Zone files are a key component of configuring DNS servers. In this lab we will configure a forward zone file, and add TTL, SOA, NS and A records. This allows a name server to resolve a query, given the hostname, and returns the IP address. This is the most common type of DNS query.
