external-ip

Finds the current external IP address contacting http and dns external services.

If at least one of the sources replies the reply with the highest occourrences will be reported as the IP address.

Three functions provides sets of known working sources.

• get_http_sources Returns all known http sources
• get_dns_sources Returns all known dns sources
• get_sources Returns all sources combined

Additionally a single igd source can be instantiated if the feature is enabled ("discover_igd"), to retrive the IP from an home router. If the feature is enabled get_sources will return it as a source too.

Runtime

It requires to run with Tokio runtime due to the depenency on hyper if you use the HTTP resolver. The DNS resolver can work with other executors at the moment. (tested with futures)

Extend

It's possible to extend how the sources dynamically via the API as long as the Source interface is implemented and it's passed as a boxed trait object.

Example

  let sources: external_ip::Sources = external_ip::get_sources();
  let consensus = external_ip::ConsensusBuilder::new()
      .add_sources(sources)
      .build();
  let result = consensus.get_consensus();
  let value = block_on(result);
  assert_ne!(value, None);
