LookUp method
IPAddr = LookUp ( AddrString )
| AddrString |
String |
A domain name or dotted address string |
| IPAddr |
Long |
The first IP address found by the DNS lookup |
LookUp converts an IP address from string to numeric format.
If AddrString is a dotted numeric address such as "127.0.0.1", LookUp
does the conversion using StringToAddr and
returns immediately.
If AddrString is a domain name, LookUp uses the Connection object in the Connection property to do an A record lookup
and returns the first IP address found. If the lookup fails, LookUp
returns 0 and sets the Error property.
