LookUp method

Syntax: IPAddr = LookUp ( AddrString )

Part Type Description
IPAddr Long The first IP address found by the DNS lookup
AddrString String A domain name or dotted address string

This method converts an IP address from string to numeric format.

If AddrString is a dotted numeric address such as "", LookUp does the conversion and returns immediately.

If AddrString is a domain name, LookUp does a DNS lookup and returns the first IP address found. If the lookup fails, LookUp returns 0 and sets the Error property.
