not working for me on 6.49.8
i dont get nothing in log and ip not updating

April 19, 2024

Still working for me, running firmware arm64-7.14.3 on an RB5009.
Also running it on an older RB2011 and an older RB951 with firmware mipsbe-6.49.14; working fine.

The script still always reports the IP was updated because it was changed, even when it hasn't changed... But it does actually update when the IP does change, and that's all that matters.

Beware that certain special characters in your NO-IP username/password may not work on a 'tik without first escaping ( \ ) them in pre-7.0 firmware. #https://wiki.mikrotik.com/wiki/Manual:Scripting#Constant_Escape_Sequences
