Entering Ip Addresses - Watchguard Firebox X1000 User Manual

Entering IP addresses

You generally enter IP addresses into fields that resemble
the one below.
When typing IP addresses, type the digits and periods in
sequence. Do not use the TAB key, arrow key, spacebar, or
mouse to jump past the periods. For example, if you are
typing the address 172.16.1.10, do not type a space after
you type "16" or try to position your cursor past the next
period to begin typing "1." Instead, type a period right
after "16," and then type "1.10."
If your address has a network mask, use slash notation to
enter it. In slash notation, a single number indicates how
many bits of the IP address identify the network that the
host is on. A netmask of 255.255.255.0 has a slash equiva-
lent of 8+8+8=24. For example, writing 192.168.42.23/24 is
the same as specifying an IP address of 192.168.42.23 with a
corresponding netmask of 255.255.255.0. The following
table shows network masks and slash equivalents.
