How DNS and DHCP work together


  • Hi,


    Thank you for your post here.


    Generally speaking, DNS and DHCP are separate infrastructure networking services which provide name resolution and IP address lease. There are several inter-function that I can remember:


    1. DHCP distribute the options such as DNS server address (006) and domain suffix (015) for name resolution on the clients.


    DNS server address (006):


    The DNS server address in the domain for internal name resolution or external name resolution.



    domain suffix (015):


    The suffix which will be append when you try to resolve single label name in the domain.



    2. DHCP will dynamically register the DNS PTR record for DHCP clients running Windows 2000, Windows XP , or a Windows Server 2003 operating system.


    Using DNS servers with DHCP


    If you have any questions or concerns, please do not hesitate to let me know.
