Does Scrapy support IPv6 addresses?
-----------------------------------
Yes, by setting :setting:`DNS_RESOLVER` to ``scrapy.resolver.CachingHostnameResolver``.
Note that by doing so, you lose the ability to set a specific timeout for DNS requests
(the value of the :setting:`DNS_TIMEOUT` setting is ignored).
