Hello, My company have server to host application for internal use only. So this server is on internet but IP are restricted only from office. Is it possible to use Let’s Encrypt to have Https ? I ask that because in the FAQ we can’t know the IP of let’s encrypt so how the validation will be done …

looking at the go alternate clients - the Lego one already supports gandi dns challenge.

From a quick look - https://wiki.gandi.net/en/xml-api - gandi has a perfectly good API for dns records, so you should be able to use the DNS method.
