IPv6 route table limits under Linux
I have been experimenting with IPv6 addressing and routing under different Linux flavors. Addressing in LANs is quite easy with Auto/Zero-Conf, however for Auto/Zero-Conf you need to use /64 network, which could lead to memory exhaustion due to a Neighbor Discovery attack (I will write more on this later, so check below for related articles). Routing is equally simple to setup with Router Advertisements.
So I wanted to go a step further and loaded a full IPv6 routing table via BGP into a linux box. Mine unfortunately had a limit in the kernel, actually net.ipv6.route.max_size was set to 4096. The BGP feed I used delivered 6419 prefixes and only 4068 were loaded into the kernel table.

ILR opens range 28 for allocation
Luxembourg’s regulator has opened the numbering range 28 for allocation to operators on July 1, 2011. The range was long time blocked for historical reasons.
Prior to May 1, 2006 the mobile network operator LUXGSM used the numbering range 028 for its mobile voicemail service. Due to the common practice to omit the leading 0 when dialing a number from abroad, the numbering range 28 was aliased to 028 when called from abroad. This obviously rendered the numbering range 28 unusable for other services.

AVM just released a new Lab firmware version
AVM has released a new Lab firmware version for the Fritz!Box 7390 and 7340. The AVM developers seem to have worked really hard, a lot of work was done on the DECT, IPv6 and NAS part. The Lab firmware now supports secure DECT repeating mode, the AVM DECT phones will be able to display pictures included in RSS feeds and use custom PM3 ringtones. On the IPv6 stack RFC5969 aka 6rd was added, DS Lite is now supported.
You can find more details on the AVM Lab Portal.
