i am using free dyn dns service on https://www.dyndns.com/
they require updating every 35 days i don't care. but the web-based updater tool is so terrible that it tends to apply the current ip address of browser in-use, which differs from my host machine's ip. the host runs remotely(from tokyo).

should they upgrade the system or should i get used to it.
