    Ubuntu Update Servers IP Addresses

    Hi,

    Does anyone know the ubuntu update servers ip addresses. I am trying to fine tune my firewall rules and was unsure of what ip addresses to use for the update servers.

    I believe they are us.archive.ubuntu.com and security.ubuntu.com. However, I could be wrong.

    Thanks for any help you can provide.

    You cannot assume that the IP address those domains resolve to will always be the same.

    Re: Ubuntu Update Servers IP Addresses

    not really a great plan as the dns will likely change based on time and locality, but you can find the info you need by looking at your sources, and then performing a nslookup or dig on the server

    hree is a dig
    Code:
    karmic:~/Downloads/skipfish$ dig www.ubuntuforums.org

    or an nslookup
    Code:
    karmic:~/Downloads/skipfish$ nslookup www.ubuntuforums.org

    Things are rarely just crazy enough to work, but they're frequently just crazy enough to fail hilariously.
