Silly Tech Tip Of The Week: Linux, DNS, and DHCP

If you are running Linux and you change from a DHCP setup to a static IP address on your local network, and then at some future time your ISP changes your external IP address and your internet slows to a crawl, you might find it useful to know that your resolv.conf file probably contains the old DNS entries set up back when you were using DHCP. It’s a simple matter to change it, but knowing the problem is 99% of this battle. Maybe this will help someone else out there some day who wonders why a Windows box on the same network is chugging along happily but your Linux box is choking. Happy surfing!
