After reading this I noticed I also have slowness in DNS resolving.
If you look in /etc/resolv.conf:
- Code: Select all
# Generated by NetworkManager
# nameserver 220.127.116.11
I disabled the line nameserver 18.104.22.168
and things go smooth again.
edit: After a tiny digg I found out it selected the windows server in this Network todo the DNS work instead off using the ISP DNS servers directly. No this doesn't answer your ipv6 question but it significantly speed up my connections.
