OpenDNS doesn't support myip, so it appears there's no way to update them with what dynamic IP address a network is using without using their OpenDNS Updater. I'm interested in this for the purpose of content filtering, not DDNS. Has anyone found a way to do this strictly from within Tomato? As a secondary question, now that I've learned this I'm confused as to what the point of having OpenDNS as a Tomato option. They're not a DDNS provider, and DNS-O-Matic is their DDNS updating service.
