I found this link, which describes an interesting new feature on IOS6. This new option to enable IFA which stands for “identifier for advertisers”, helps advertisers with giving them an unique ID so they can ad targeting that user.
If you don’t like this you can disable IFA via:
Setting -> General -> About -> Advertising; in this menu you can put Limit Ad Tracking to ON.

Since my previous Asus WL-500gP was broken due to a power outage, it was time for a new one. Some requirements for a new router where; IPv6, 802.11a/n and gigabit Ethernet switch ports. The Asus only had the IPv6 requirement since I installed OpenWrt on it.
The Cisco EA4500 was one that supports all this. Since I quickly needed a new router I bought this one at a local reseller.
I installed this router at home and found out that this router supports native IPv6, but only via auto-configuration and DHCPv6. Manual IPv6 addresses cannot be configured and static IPv6 routing is also not an option.
Since my previous setup was static routing with IPv6, I needed some changes on the Internet Service Provider side. Luckily I do the configuration and administration for this ISP as a day job. So I introduced DHCPv6 as a configuration option for customers.
This is very easy to setup. The router on the ISP site is an Cisco ASR 1002, with an ATM interface to a DSL provider.
First the configuration for static IPv6 routing was as follow (only IPv6 relevant commands):
interface ATMx/x/x.xx point-to-point atm route-bridged ipv6 ipv6 address 2001:xxxx:xxxx:xxxx::x/64 ipv6 enable ! ipv6 route 2001:xxxx:xxxx:xxxx::/64 ATMx/x/x.xx 2001:xxxx:xxxx:xxxx::x
Now the configuration with DHCPv6 is (again only IPv6 relevant commands):
interface ATMx/x/x.xx point-to-point atm route-bridged ipv6 ipv6 address 2001:xxxx:xxxx:xxxx::x/64 ipv6 enable ipv6 nd other-config-flag ipv6 dhcp server ipv6-dhcp-pool ! ipv6 dhcp pool ipv6-dhcp-pool prefix-delegation 2001:xxxx:xxxx:xxxx::/64 xxxxxxxxxxxxxxxxxxxxxxxx dns-server 2001:xxxx:xxxx:xxxx:x dns-server 2001:xxxx:xxxx:xxxx:x
The EA4500 on the client side does a DHCPv6 request. The ASR on the ISP side replies and sends a prefix for the local LAN side and the DNS servers. The EA4500 advertises the /64 prefix and its own IPv6 address for DNS resolving on the local LAN via router advertisements (RA).
This weekend I was busy with another hobby of me; photography. I use a Canon 400D and this weekend I used my Canon EF-S 15-85mm f/3.5-5.6 IS USM lens. I really like this lens a lot since you have a broad view when you put it at 15mm, but also that little extra zoom when you put it at 85mm.
Together with Michael, a good fiend of mine, we went to the carnival in Breda and we both took our 400D’s. It was raining a little, but since we’re able to take some nice pictures, it was worth the effort.
The next day we went to the city center of Breda. We just walked around and took pictures about everything we thought was good enough for a photo. After a lot of photographs we went home, touched the pictures a little bit on the computer and we posted them online on ravenet.nl.
We think we made some nice pictures. Please let me and Michael know what you think about them. Wether you like it or not, we had a great weekend.
