I have a project in Jython 2.5 (with JRE/JDK8) which connects to a secure SOAP web service, hosted on a local server. The client program runs on Windows 10, and uses suds(suds-jurko) to call operations on the web service. The SSL certificate for the service is self-signed and has been added to the local cacerts file. Since the web service is on a local server, access to the service is via the server's IP address.
The problem I face is that communication with the web service is very slow, as it attempts to do a reverse DNS lookup on the web service's IP address. Each reverse lookup fails (which is expected), but it waits 1.5 second between each attempt, resulting in an overall delay of about 5 seconds per call.
This issue seems to be fairly well documented (here, here, here, generic google searches for 'java ssl reverse dns lookup', etc.), but the general solutions seems to revolve around either modifying the HOSTS file on the client machine, or pass some hostname to InetAddress when creating the SSL connection to prevent the reverse DNS lookup. The first option is not practical for my case, as there are multiple clients and it would be less than ideal to modify the HOSTS file on each client machine, and I don't know if the second option is viable when using suds.
Note that I have not provided source code as I believe it will unnecessarily complicate the question, but calls are made using the suds API, e.g.:
client.service.method(params)
Is there anything I can do, given that I'm running Jython 2.5/suds, to prevent the reverse DNS lookup, and I want to address the server via its IP address and not modify the HOSTS file?
