Apple IP (AppleShare IP) Gateway - Manual (Page 40)

5 Click Manually in the Obtain Address section of the dialog box, then click OK to return to
the MacTCP control panel.
6 Enter the IP address of the gateway computer in the lower section of the control panel.
Obtain this address from your network administrator and type it exactly as
specified.
7 Click More.
The Administrator dialog box reappears, with the following information now
included:
m the IP address itself
m an address class indicated in the Class pop-up menu
m a network identifier
m a host (node) identifier
The address class and the network identifier are assigned to any network that
accesses the Internet by the Internet’s central authority, the Network
Information Center. Classes range from A, for very large internets, to C, for
small local area networks. Host identifiers are locally set.
8 If your network requires subnetwork addressing, set the subnet mask and subnet
address by dragging the Subnet Mask slider.
Subnetwork addressing is a technique that allows groups of networks on an
internet to share a single network number, in much the same manner as a large
group of postal addresses share a zip code. Obtain the correct settings from
your network administrator. When you slide the bar, the Subnet field fills in
and the Node field changes. The Net field stays the same.
9 Fill out the Domain Name Server Information section of the dialog box.
The domain name system was created so that users could work with relatively
easy-to-remember symbolic names instead of more opaque numerical
addresses. A domain name server keeps a record of names assigned to
networks and matches them to their numeric equivalents. Obtain the domains
and IP addresses of your available domain name servers, as well as the correct
server to use as the default setting, from your network administrator.
