Bootp-dhcp-parametrit

Bootstrap Protokolla (BOOTP) [RFC951] kuvaa IP/UDP-käynnistysprotokollaa, jonka avulla levytön asiakaskone saa oman IP-osoiteen, palvelinisännän osoitteen ja josta tiedosto ladataan muistiin ja suoritetaan. Dynaamisen isännän konfikurointi protokolla (DHCP) [RFC2131] tarjoaa puitteet IP-isäntien automaattiseen konfigurointiin.
