The Agilent 33210A assumes that all IP addresses and other dotnotation
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
