OpenDNS, in Holland soon.

Some days ago I read something about OpenDNS [thinking of] getting a new location [AMS-IX] for their excellent DNS service. Since it is based on anycast, endusers need not to change any addresses in order to benefit from the added location. Silly me, I can't find the article anymore.

Last week I had some issues with slow dns lookups/slow Internet on Leopard again. It is plagued with issues. My setup with an Apple Airport and Apple iPhones, and an iMAC, a G4 & more [all running 10.5.7] is often experiencing issues with name resolving. Unfortunately, I am not the only one with this. I have googled my arse off and tried every 'tip' I found, from turning of ipv6 in Firefox & the Airport & on my laptop to moving the resolving from my laptop to the Airport. Nothing works reliable.

Last week however the issue was another:

A simple routing loop at my provider. It took me over 30 minutes to find, focused as I was on the 'normal' DNS problems with OSX. Only after the reliable 'turn Airport off' & 'turn Airport on' trick did not work I checked the availability of the OpenDNS servers...

Other sillies with OSX:

- Calling an IP address in the 169.254./16 range 'self assigned' even if you get it from a DHCP server

- Falling back to 'old' IP addresses even if a new lease has been accepted and used

- Slow poke ethernet link setup [need to nail arp settings to flash routers fast enough]
