dhcpcd vs BIND Comments
As far as I know, dhcpcd's only relationship to DNS is that it makes the DNS server's IP address available to the host on which it runs.
they do very different things. dhcpd provides network initialisation to clients on the local subnet. bind provides name resolution to clients from local to global.

- dhcpcd is Free and Open Source
Other protocol: DHCP provides IP addressess pool for internal use and DNS provides (among other) internet names translation
