All over the internet I see example of how to set up dhcpd with WAPD proxy auto configuration using DHCP. In the
/etc/dhcpd.conf file there are statements like this:
option wpad code 252; "http://wpad.url"; option wpad code 252 = text; "http://wpad.url";
What is code 252, where is it defined and what does it mean. Why is it a number 252 and not a useful statement like wpad-proxy-url; Why use 252 and not some other number (0, 5000). I get that it works, it just does not make any sense to a human (me). Googling for what is option 252 has been fruitless.
