If your using steam, you can go into game properties and set Proton as the compatibility tool. Depending on the age of the game, you might have to switch versions of Proton.
You can use https://www.protondb.com/ to check the compatibility issues and suggested versions by the community for specific games too.
If this is for DynamicDNS, I host my DNS at cpiudflare for my domain and use a script which performs a lookup every 15 mins. It uses CF’s API to then update the record if it changes.
For DNS resolution, I use pi hole quad9 resolvers
Edit: sorry, just re-read and realised your talking about DNS hosting for a domain. honestly I use my Cloudflare or my domain provider. Given a single IP is a point of failure, it makes sense to have multiple NS on different networks/IPs. You also have to take into account Glue records and while not required, reverse DNS is also good. If you have Dynamic IPs it’s not worth it since glue records will need changing and those are manual each time
I found this the other day: https://revolt.chat/
I have yet to deploy it but from what I’ve seen it’s a discord alternative
Try using this and sent it a test mail: https://www.mail-tester.com/
It’ll check blacklists, configuration, DNS and mail content itself for any issues
Paper Please. They tell multiple stories, some you can invest and follow or cut short with a simple button (DETAINED!). The gameplay is also interesting, having to maintain and follow all these little details reminds me of some brain training games. The comedic writing as well of some of the characters is also brilliant (looking at your Georgi).
Honestly any service that offers cPanel can allow mail hosting and a catchall.
If you just want a basic IMAP/SMTP service with nothing fancy I know these guys do allow catch all mailboxes https://hostinguk.net/email
As far as I’m aware this won’t be possible. You’d have to rebuild the site from scratch and manually copy images and text over.
As for SEO, I would expect a lot of the meta data to change since wordpress will be interpreting a lot of that.
As long as the domain stays the same, you could would probably get away with redirecting links, however I would expect your ranking to drop for a bit after the immidiate move regardless.
I know, I was just tryna point out the silver lining
