softkey and enter
the domain name. The domain name is translated into an IP address.
The domain name is entered as a string using the knob and cursor
keys to select and change characters. The domain name may include
letters, numbers, dashes (“-”), and periods (“.“). You can use the
keypad for the numeric characters only.
Press to delete all characters to the right of the cursor position.

More about IP Addresses and Dot Notation
Dot-notation addresses ("nnn.nnn.nnn.nnn" where "nnn" is a byte value)
such as IP addresses must be expressed with care. This is because
most web software on the PC will interpret byte values with leading zeros
as octal numbers. Thus, "255.255.020.011" is actually equivalent to the
decimal "255.255.16.9" rather than "255.255.20.11" because ".020" is
interpreted as "16" expressed in octal, and ".011" as "9". To avoid confu-
sion it is best to use only decimal expressions of byte values (0 to 255),
with no leading zeros.
The
Keysight
33210A assumes that all IP addresses and other dot-nota-
tion addresses are expressed as decimal byte values, and strips all lead-
ing zeros from these byte values. Thus, if you try to enter
"255.255.020.011" in the IP address field, it becomes "255.255.20.11" (a
purely decimal expression). You should enter exactly the same expres-
sion, "255.255.20.11" in your PC web software to address the instru-
ment. Do not use "255.255.020.011"—the PC will interpret that address
differently due to the leading zeros.
