How TO convert an IP Address to a IP Number?
IP address (IPV4) is divided into 4 sub-blocks. Each sub-block has a different weight number.
To calculate IP Number the formula is given below
IP Number = 16777216*a + 65536*b + 256*c + d
where
IP Address = a.b.c.d
For example, if IP address is “127.4.5.13“, then its IP Number would be
IP Number = 16777216*127 + 65536*4 + 256*5 + 13
= 2130706432 + 262144 + 1280 + 13
= 2130969869
