num2ipv4() / ipv42num()

num2ipv4

num2ipv4(int)

Converts an integer into an IPv4-address and returns the address as string. Input is an integer with a value between 0 and 4294967295. The output format is ‘>decimal<.>decimal<.>decimal<.>decimal<’ and ‘-1’ if the integer input is invalid or if the function encounters a problem.

ipv42num

ipv42num(str)

Converts an IPv4-address into an integer and returns the integer. Input is a string; the expected address format may include spaces in the beginning and end, but must not contain any other characters in between (except dots). If the format does include these, the function results in an error and returns -1.
