Module: PacketFu::IPHeaderMixin

Included in:
HSRPPacket, ICMPPacket, IPPacket, TCPPacket, UDPPacket
Defined in:
lib/packetfu/protos/ip/mixin.rb

Overview

This Mixin simplifies access to the IPHeaders. Mix this in with your packet interface, and it will add methods that essentially delegate to the ‘ip_header’ method (assuming that it is a IPHeader object)
