I've been turning off various services, and am wondering about bootpc, which is listening on port 68. According to Debian package info, bootpc is a bootp client. According to the Webopedia, bootp is

"Short for Bootstrap Protocol, an Internet protocol that enables a diskless workstation to discover its own IP address, the IP address of a BOOTP server on the network, and a file to be loaded into memory to boot the machine. This enables the workstation to boot without requiring a hard or floppy disk drive. The protocol is defined by RFC 951."

This doesn't sound like something I need? Or is it?
