url.c:parse_proxy sets the proxy name to "2a00" and overrides the port with 0, as it tries to parse "fac0:a000::7:13" as a port number. Is this a bug or expected behavior?
Unfortunately the documentation at http://curl.haxx.se/libcurl/c/CURLOPT_PROXY.html doesn't mention if IPv6 addresses have to be in square brackets even if they don't contain a port number or a scheme. If so, probably the documentation should reflect that and parse_proxy should return an error if the port string is invalid.
The text was updated successfully, but these errors were encountered:
If the port number in the proxy string ended weirdly or the number is
too large, skip it. Mostly as a means to bail out early if a "bare" IPv6
numerical address is used without enclosing brackets.
Also mention the bracket requirement for IPv6 numerical addresses to the
man page for CURLOPT_PROXY.
