I am using DYNU for ddns settings. For my internal DD-WRT for AP + Switch, I have to Use external IP check warnings. However, in the DDNS Status (logs), there are lots of warnings: RC_DYNDNS_INVALID_RSP_FROM_IP_SERVER.

Tue Feb 22 13:29:25 2022: W:'RC_DYNDNS_INVALID_RSP_FROM_IP_SERVER' (0x42) updating the IPs. (it 2)
Tue Feb 22 15:09:12 2022: W:'RC_DYNDNS_INVALID_RSP_FROM_IP_SERVER' (0x42) updating the IPs. (it 11)
Tue Feb 22 15:31:26 2022: W:'RC_DYNDNS_INVALID_RSP_FROM_IP_SERVER' (0x42) updating the IPs. (it 13)
Tue Feb 22 16:04:43 2022: W:'RC_DYNDNS_INVALID_RSP_FROM_IP_SERVER' (0x42) updating the IPs. (it 16)

These warning may not appear every 10 minutes, but seems dd-wrt is doing something every 10 minutes, and report warnings.

Saw some posts that it may be related to external ip server, how can I fix/supress this warnings, at least make these warning a lot less?

I am thinking if I put
Additional DDNS Options: --ip_server_name checkip.dyndns.org:8245 /
or
Additional DDNS Options: --ip_server_name whatismyip.org:80 /
or
--ip_server_name ip.changeip.com /

checkip.dyndns.org seems the default one if not specified, not sure the default port though.


Not sure if it works, and what are the impacts, good or bad.
