Few days ago there was a sale on Namecheap.com and i got a domain for a 0.89$. Mostly because DynDns.com has
drastically shrunk canceled their free services, I wanted it for personal use for my home machine that gets IP dynamically. Since I’m a fan of DD-WRT and have been using it for quite a while on my home router, I wanted it to update my DNS record when its IP changes. Out of the box DD-WRT doesn’t support Namecheap’s DDNS service but can be customized to work with it.
After an hour or so of testing and googling, here is the only configuration that i managed to get working on latest release of DD-WRT v24-sp2 (05/27/13) std (SVN revision 21676).
password you got from namecheap ddns service
hostname or enter @ if you want to point directly to your domain
Note: Don’t enter anything after
&host= even if you have a subdomain.
