- Synopsis:
- $convert(<ip address|hostname>)
-
- Technical:
- This function does a DNS lookup on the given address. For an IP address,
- it attempts to find the corresponding Internet hostname. For a hostname,
- it attempts to find the corresponding IP address.
-
- Practical:
- This function does effectively the same thing as $iptoname() and
- $nametoip(). It is mostly useful when you want to convert an address,
- but you aren't sure if the input will be an IP address or not.
-
- Returns:
- IP address or hostname corresponding to input, or nothing on error
-
- Examples:
- $convert(some.school.edu) returns IP address for "some.school.edu"
- $convert(192.168.1.1) returns hostname for "192.168.1.1"

- iptoname(6); nametoip(6)
