HI Uli, Thats not actually in decimal. It's a 32 bit number in dotted decimal notation. Just like an IP address is normally dotted decimal, it can also be one binary 32 bit number...
127.0.0.1 = 01111111.00000000.00000000.00000001 = 0111111100000000000000000000001 Which we can make into decimal 2130706433 Try this one in your web browser and see what happens... 3494206055 :) So that's binary and decimal and dotted decimal explained... Same goes for OPSF areas... 0.0.1.1 = 00000000.00000000.00000001.00000001 = 100000001 = 257 Hope this helps.
