More About Dot Notation: Dot-notation addresses ("nnn.nnn.nnn.nnn" where
NOTE
"nnn" is a byte value) must be expressed with care, as most web software on the
PC will interpret byte values with leading zeros as octal numbers. For example,
"255.255.020.011" is actually equivalent to decimal "255.255.16.9" not
"255.255.20.11" because ".020" is interpreted as "16" expressed in octal, and
".011" as "9". To avoid confusion, use only decimal expressions of byte values (0
to 255), with no leading zeros.
For example, the 33210A assumes that all dot-notation addresses are expressed
as decimal byte values and strips all leading zeros from these byte values. Thus,
attempting to set an IP address of "255.255.020.011" will become
"255.255.20.11" (a purely decimal expression). Be sure to enter the exact
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 this address differently due
to the leading zeros.
Subnet Mask (LAN)
Subnetting allows the network administrator to divide a network into smaller
networks to simplify administration and to minimize network traffic. The subnet
mask indicates the portion of the host address to be used to indicate the subnet.
– You need not set a subnet mask if DHCP or Auto IP is in use.
– Contact your network administrator to find out whether subnetting is being
