RE: BCMSN Hex- IP to MAC

Tue, 14 Nov 2000 11:13:43 -0800

it is a nice trick, but too much work for a lazy guy like myself. :->
 
I just memorize the table - it works a lot faster
 
we all know what 1-9 is in binary, or can count it up easily.
 
A=1010=10
B=1011=11
C=1100=12
D=1101=13
E=1110=14
F=1111=15
 
write it down on the paper before you start the test. refer to it when necessary.

Cool trick. Hadn't seen that one before. As I look at it, it actually does the same thing as the method I posted, but skips the binary conversion step (splitting the one octet into two quartets is equivalent to dividing by 16).

you can also go from decimal to hex by dividing by 16 example given 235
 
235 / 16 = 14 with a remainder of 11
14 in hex is E
11 in hex is B
answer EB
 
Another example 149
168/16 = 10 with a remainder of 8
10 in hex is A
8 in hex is 8
answer A8 hex
 
To convert hex to decimal is just as easy take the left most hex digit and multiply it by 16 then add the right digit
EB in hex
E * 16
E=14
14*16 = 224
B=11
224 + 11 = 235
