Resolve a Hostname to an IP Address

See more Socket/SSL/TLS Examples

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.
