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.

func chilkatTest() {
    let socket = CkoSocket()!

    //  Resolve a hostname to a numeric IP address, waiting up to 5 seconds.
    var ipAddress: String? = socket.dnsLookup(hostname: "example.com", maxWaitMs: 5000)
    if socket.lastMethodSuccess == false {
        print("\(socket.lastErrorText!)")
        return
    }

    print("Resolved IP address: \(ipAddress!)")
