    Just log into you hosting site or external DNS site (DNS Manager) and create an A record.  You might also have to let your ISP know because they might block it.  On another note (like sarang_tinguria asked) what is the purpose.  You want to be careful when it comes to resolving external addresses to internal ones.

    without knowing what you are trying to do..
    if the above answers dont help (and Neilsr is the most likely solution - although read it as "create an A record")

    perhaps you want to forward the external Ip address to the internal IP - which would be done on your internet router - assuming the external Ip is your fixed IP address - you then use firewall rules or port forwarding to forward data to your server - eg forward port 80 to make your server act as a web server.

    Good luck - feel free to give us all more info on what you are trying to achieve

    You cannot do this through DNS manager.

    You need to configure this on a firewall or router; either as a NAT'ed Address or published via a firewall rule on something like ISA.
