Resolve a Hostname to an IP Address

Demonstrates Socket.DnsLookup, which resolves a hostname and returns one numeric IP address.

Background. A maxWaitMs of 0 waits indefinitely; a positive value bounds the wait. Resolved results may be served from Chilkat's process-wide DNS cache.

#  Resolve a hostname to a numeric IP address, waiting up to 5 seconds.
ipAddress = socket.dnsLookup("example.com",5000)
