    I have 2 IP's in my OpenDNS network, do I have to install the Updater for each computer, or will one updater update both computers?

    Are they on the same network, or two different networks? If they are on the same network, with the same WAN address then you only really need one to update your IP when it changes. Better to install it on both though.

    If by two IPs you mean two *public* IP addresses, then you need to install it on at least one computer for each IP address.

    Both IP's are on the same network, they are just my 2 computers on my home network.

    OK, then I think you are misunderstanding the difference between public IP and private (LAN) address space. http://www.opendns.com/support/article/193


    http://www.faqs.org/rfcs/rfc1918.html
    10.0.0.0 - 10.255.255.255
    172.16.0.0 - 172.31.255.255
    192.168.0.0 - 192.168.255.255

    Anything in those ranges is a Private address.

    If you actually have two public addresses, this will require creating two OpenDNS networks, and you would need to run an updater behind each IP.

    Both my computers have public IP's. I have installed the updater for both computers, thanks.

    You have multiple dynamic public IP addresses? That is an odd configuration unless you have two ISP's.

    No ! Some ISP actually provide more than one dynamic IP.
    My ISP provides up to 5 IP adresses and the Router does not use NAT. It is like having 5 differnt subscriptions, but scharing the bandwith... BUT I have connected A NAT-Router behind the ISP unit to be able to share printer and disks in A secure manner... That means I only use 1 IP of 5 possible...

    Again, that's a very odd model for the ISP. IP's are limited so for an ISP to give out 5 dynamic IP's is not the norm. Giving out 5 statics is one thing, since you are probably using the static IP's for something.
