The only advantage to DHCPCD that I know of is it allows you to run scripts 
after it receives a new IP (i.e. firewall scripts).  The 10.x.x.x is by 
definition a private IP and shouldn't be for the cable modem. It sounds like 
pump/dhcpcd is not running when you restart the network and the NIC is 
assigned a default IP (10.x.x.x).

My experience with cable modems and DSL is that the IP you receive should 
stay the same unless you shutdown for long periods of time.  I always ran 
pump without any problems.

No clue on the different IPs for the different DHCP clients, though.

Good Luck!
