Async DNS resolution, with all the DNS features you need!
Join our Discord for any questions and friendly banter.
Add the package:
.package(url: "https://github.com/orlandos-nl/DNSClient.git", from: "2.0.0"),
And to your target:
.product(name: "DNSClient", package: "DNSClient"),
Connect to your default DNS Server:
let client = try DNSClient.connect(on: loop).wait()Connect to a specific DNS Server:
let googleDNS = SocketAddress(ipAddress: "8.8.8.8", port: 53)
let client = try DNSClient.connect(on: loop, config: [googleDNS]).wait()Resolve SRV Records:
let records = try client.sendQuery(forHost: "example.com", type: .srv).wait()Resolve TXT Records:
let records = try client.sendQuery(forHost: "example.com", type: .txt).wait()Resolve PTR Records:
let records = try client.ipv4InverseAddress("198.51.100.1").wait()
let records = try client.ipv6InverseAddress("2001:DB8::").wait()Need I say more?
The DNS Client doesn't retain itself during requests. This means that you cannot do the following:
DNSClient.connect(on: request.eventLoop).flatMap { client in
// client.doQueryStuff()
}The client will deallocate itself, resulting in a timeout. Make sure that the client is strongly referenced, either until all results are in or by setting it on a shared context. In Vapor, that can be the request's storage container. On other services, you could consider a global, ThreadSpecificVariable or a property on your class.
