It seems to depend on the ip he choses to assign to me. Outgoing sockets work. Incoming sockets dont reach me. Problems began when they started using 84.167.xx.xx for their DSL-customers at the end of 2004. Support does not answer my emails. Maybe they dont even get them. I do have problems sending emails to a lot of places using this ip address range. If I was not afraid that a lot people are facing that very same problem, probably without even knowing, I would not bother you. There are no firewalls between the two computers neither in hardware nor in software and there are no NAT-routers involved either. This is the second trial to send this email.

New IPv6 Address Block Allocated to RIPE NCC
by leo vegoda 20 Jul '05

20 Jul '05

Dear Colleagues, The RIPE NCC received the IPv6 address range 2A01:0000::/23 from the IANA in July 2005. We will begin making allocations from this block in the near future. You may wish to adjust any filters you have in place accordingly. More information on the IP space administered by the RIPE NCC can be found on our web site at: https://www.ripe.net/ripe/docs/ripe-ncc-managed-address-space.html This document has been updated to to provide extra information about the IPv6 address space we manage, following some requests we received. I hope people find the new format useful. Regards, -- leo vegoda Registration Services Manager RIPE NCC
