( Refer “ Understanding DHCP Option 82 ” post for basic understanding of this feature) Here is the topology for this post. ISC DHCP and option 82 The Relay Agent Information Option aka Option82. On DSL access networks that use DHCP to assign an IP address to the enduser, it is usual that some network element along the way acting as a DHCP relay stuffs a so-called 'relay agent information option' aka "option 82" into the DHCPDISCOVER packets.
