Net_DNS_Packet

The Net_DNS_Packet class provides methods for creating a DNS packet suitable for sending to a nameserver. It also provides the methods of parsing a response from a nameserver into a Net_DNS_Packet object.

A standard DNS packet is made up of five main pieces:

• Header

• Question Section

• Answer Section

• Authority Section

• Additional Section

Net_DNS defines the DNS packet header as a Net_DNS_Header object. Net_DNS_Question defines the question section of a packet object. The remaining three sections should be arrays of Net_DNS_RR objects.
