Do you really mean "ping the IP" - if your IP address ix 1.2.3.4 then, when
you ping that, nothing else can answer.  If you mean that your machine is
named "MyMachine", and you ping mymachine.domain.com and get a response
back from somewhere else, then you need to force your dhcp client to send
the hostname to the DHCP server.  With dhclient3 that's
(in /etc/dhcp3/dhclient.conf):

  send host-name "mymachine";

Some clients accept "hostname mymachine" in the /etc/network/interfaces
file.
