dns-set-servers function fails to set dns-servers on Windows with IPv6 available network. (progn (require 'dns) (dns-set-servers) dns-servers) -> (nil) The reason is that Windows's nslookup program returns server's IPv6 address if availeble but dns-set-servers function assumes that server's address is always IPv4. > C:\>nslookup localhost > サーバー: server.lan > Address: xxxx:xxxx:xxxx::1 > > 名前: localhost.lan > Addresses: ::1 > 127.0.0.1 # "サーバー" and "名前" are Japanese translations for "Server" and # "Name", respectively.
