    dhcp ddns question


    I have a problem. I want the folowing, and was wondering how to do it.

    We have pc's who get a dynamic dhcp number AND pc's which has a static reservation in the dhcp server. So there is both ....

    No we have dynamic dns working, forward en reverse zone is being filled, no problem. BUT ......

    We only want the dhcp server to send a dns update to the dns server if the pc has a static reservation. Because we want to prevent weird names, like :
    We only want : host01 etc.....

    We have a very large campus, so we have to fix this.

    Does anyone know if this is possible.

    DNS : Bind
    DHCP : ISC (Solaris but the same under Linux)

    Thank you for any help.

    So what you're saying is that you only want static IP addresses to be provided by the dns system? This is surely configurable in the DHCP config, stop it providing dynamic dns updates to the DNS service, and turn off dynamic updates in the DNS server just to make sure.

    While I have dhcp on my server, I have it ser up so that all the hosts are allocated the same IP address each time they connect - and I dont bother with dynamic dns at all.
