And around here a lot of leftist spaces enable you to have fun while spending little to nothing. Dirty punk concerts for a low cover charge and beer almost as cheap as in the store. And most of not all of those prices are "pay less if you can't afford it".
Other than that if agree with other commenters. Knowing spaces/people to hang at/with. I'm perfectly fine spending time in my one bedroom if I'm not alone all the time there so having some friends over, even if it might be crammed, and just shooting the shit is a simple and affordable way to have a good time
I had used duckdns for a while back in the day. Always worked great.
These days I have a domain at namecheap which provides a DynDNS feature as well so I'm using that.
