Deriving an
IP Address from
a Media Access
Control (MAC)
Address
The 32-bit default IP address for the STB NIP 2212 is composed of the last four
octets of its 48-bit Media Access Control (MAC) address. The MAC address, or
Institute of Electrical and Electronics Engineers, Inc. (IEEE) global address is
assigned at the factory. The MAC address for an STB NIP 2212 is located on the
front bezel under the Ethernet port (See External Features of the STB NIP 2212,
p. 24).
A MAC address is stored in hexadecimal format. The numbers in the MAC address
must be converted from hexadecimal to decimal notation to derive the default
IP address. Use the following steps:
Step
Action
1
A MAC address comprises six pairs of hex values, e.g., 00 00 54 10 01 02.
Ignore the first two pairs: 00 00.
2
Identify a pair, e.g., 54.
3
Multiply the first number, 5 by 16. (5 x 16 = 80).
4
Add the second number, 4 (80 + 4 = 84).
Note: There are many resources for converting hex numbers to decimal numbers.
We recommend using the Windows calculator in scientific mode.
Note: If you set the lower rotary switch to either INTERNAL position (See Rotary
Switches, p. 28) and no IP parameters have been assigned from the
STB NIP 2212 web site, the STB NIP 2212 is configured with its derived default
address when it is powered on.
