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.
