Convert this number

3516293025


From dec to a IP address ??

thanks!

huh? Ip addy's are in decimal, there sint a conversion.

You've got Hex, Binary, and Decimal.. there isnt an "IP". Its probably just encrypted or something

or maybe i just dont understand your question

Sorry.. Ill be clearer.

an ip address is a 4x 4byte dec numbers.

10.10.5.3

he took the number and went to bin..

1010101001010011 (10.10.5.3)

then got a 16byte integer

I need to get it back to the 10.10.5.3 =)

Use shift (>>) and bitwise and (&) to split it up into the four bytes, then concatenate them with dots.

You're mistaken about the IP btw. An IP in the xxx.xxx.xxx.xxx representation is 4 1-byte integers, and the number you have is a single 4-byte integer.

You can use modulo and division to get the original number, but bit shifting is faster.
