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
confusion it is best to use only decimal expressions of byte values (0 to
255), with no leading zeros.
The Agilent 33500 Series assumes that all IP addresses and other dot-
notation addresses are expressed as decimal byte values, and strips all
leading 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
expression, "255.255.20.11" in your PC web software to address the
instrument. Do not use "255.255.020.011"—the PC will interpret that
address differently due to the leading zeros.
