How to access website via IPv6 with Groovy or Java
I'm trying to access a webpage via IPv6 but always get a "NoRouteToHostException: No route to host". I tried the following:
println 'http://[2001:4810:0:0:0:0:0:110]:80/'.toURL().text
results in:
Caught: java.net.NoRouteToHostException: No route to host
java.net.NoRouteToHostException: No route to host
at IPv6Tester.run(IPv6Tester.groovy:116)
then I tried:
def authSite = new groovyx.net.http.HTTPBuilder( 'http://[2620:109:c00d:100:0:0:c765:a381]:80/' )
println authSite.get( path: '/search/users' ) { resp, headers ->
println "response status: ${resp.statusLine}"
}
which resulted in:

The same happens with Jsoup:
def profilePage = Jsoup.connect('http://[2001:4810:0:0:0:0:0:110]:80/').userAgent(USER_AGENT).timeout(TIMEOUT).get()
Caught: java.net.ConnectException: No route to host

Btw. if I open a Socket from my IPv6 to the remote IPv6 I can read the root page (but not a specific path on the server).
I assume that I have to use a Socket with a bound local IPv6 address to access the remote IPv6 Adress but I couldn't find a way to do so. Any help would be appreciated!
The error you received, "No route to host", is correct.
Neither of the IP addresses you are trying to reach is routable or reachable from the global Internet.
To resolve the problem, connect to a valid, live IPv6 address.
