The hostname could be changed right after sending discover/request and it will take a long while before the new one is send. > In change 229476 I noticed there is a constant 0x1fff that you've moved > around.

For example I started removing 'ifi' global variable, which I really don't like, but decided to leave it for now (later I only changed variable name in disassoc() that shadowed this global variable). > In the send_packet_* function declarations in dhcpd.h, you have included > variable names which is inconsistent with the surrounding definitions.
