In preparation for some robotics I've dug out my Raspberry Pi 2 B and I'm reacquainting myself with it. Tonight's goal: Boot up an old Raspbian Squeeze SD card and get the Pi to identify on the LAN with a domain-name -- rather than having to learn it's IP address -- using avahi (AKA Bonjour or zero-conf mDNS networking).
Lately I've been noticing significant DNS latency when visiting certain sites. This is most obvious when my browser spends ages with "Looking up some.web.server.com..." in it's status bar. It's particularly bad at sites like wordpress.com where many pages make reference to sub-domains of wordpress.com and typically also to google.com for analytics or ads.
While my ISP's DNS infrastructure is pretty good, there are a couple of things I can do to improve DNS look-up, which makes page loads a lot quicker.
