As far as I know, Mullvad does not offer dedicated IP[1]. However, according to my experience, I do get the same IP if I stay connected to one server for a long time with occasional disconnects. Not sure if it's part of the algorithm or just randomness at play though. CMIIW.
Normal IP addresses with VPN can sometimes change a little, but they are usually the same.
It won't be a problem if this change happens because country and city location will stay the same.
Static IP addresses is something different, but I don't know in Mullvad is offering them.
For now, I am just using x to read stuff.
I do have an account , but i just use it if I am forced to for any reason.
I don't really like that X. I don't know why, but i just prefer other social media networks.
So you can access X website, and BR government is not blocking access?
I don't like that X, facebook and all other social networks are not allowing you to read posts if you are not logged in.
For twitter you can partially bypass this using Nitter and extensions like LibRedirect but it is getting harder.
