WebApp: SSL cert change can trigger WebApp ip change ?

[Michal Garcarz]

Hello Team,

Web Application deployed in S1 app service plan. I have read on the documentation (

Exam Ref 70-532 Developing Microsoft Azure Solutions) that:

"Deleting and re-adding the SSL certificate" "will likely yield a new IP address for the website".

Why ? Is looks like a very undesirable behavior. Could you please confirm this ?

Thanks,

Michal

adding certificates to the app service plan will not trigger anything, however chaing the binding to you web app could result in a new IP, but you can choose static on the web app.

But unless you are using a root domain name like mydomain.com, then i would suggest you not use static ip and use CNAME instead, as long as its a sub domain like myapp.mydomain.com then you can use CNAME. Remeber to keep the DNS TTL low when using cname.
