hi everyone,
I was just about to self-host a Ghost blog but then was warned that my ISP might change my external IP address at any time, so I would need to pay for a static IP address.
Is that true?
(I’d not seen much about that in stuff I’ve looked up so far about self hosting)
You don’t need a PTR record though. I just use DKIM and SPF and have no issues.

Yes you do need a ptr. The big services will outright block you.
Google I know for sure does not. They don’t even list it as a requirement. https://support.google.com/a/answer/174124?hl=en
The first link in my previous comment is literally gmail returning an error because no ptr…
Edit: your page is about setting up dkim while using their workspaces. You don’t control their ptrs.
