Hi Pierre_Roman ,

thank you, this article is great!

 

Anyway, if I'm facing with frequent IP changes in the client side (the scenario is IoT with mobile Internet connection like 4G), could it be possible to configure more frequent updates?
Let's assume for instance that the IP is updated by the ISP every hour and I want to make sure that the update is managed every 10 minutes, I should change accordingly:

1. cron job: scheduled run every 10 minutes,

2. DNS A record TTL: now the TTL has to be set to 600 to have it refreshed every 10 mins

 

Is it a viable modification or should I have to consider anything else?
Any toughts about it?

Thanks in advance for your advice!
Luca
