Hello:
Currently, the DHCP logic assumes that if a gateway is received in the DHCP
packet the boot server is on a remote network. Given that CIDR is now over 20
years old, I think it is a safe assumption that a netmask will be offered in
DHCP options.
Can this be removed? Or is there still a need to cover the classful case?
Thank you for any attention you can pay this matter.
