windows server 2008 dns

im trying to setup some dns/ptr records for my home network lab, right now i have entry's of "computer1.lab.local" or computer2.lab.local, and im trying to configure my dns to put entry like

computer1.lab.local > dhcp-192-168-1-12.lab.local

computer2.lab.local > dhcp-192-168-1-13.lab.local

i've seen some companies and businesses do that but im not sure how thats done,

anyone here know??
