[16:06] <linuxr_> hi everybody. Today I had some problems to connect to various services (apt-get update, IRC,..); no connection could be established, or only veeeery slowly. I noticed that the services attempted to connect to ipv6 addresses, so I disabled IPV6 and now everything works normally again.
[16:07] <linuxr_> However, I wonder why IPv6 was enabled on my system
[16:07] <linuxr_> can someone give advice?
