Basic question what is the actual web address

It’s been a while since I have authored anything on the web and I thought I might just set my Domain to be redirected to a url hosted on Dreamhost . I found the links to FTP - and see my directory but I’m confused . My domain name sits with Namecheap – how do I work out what the actual address is to configure the redirection? I just want to use my own html files

you need to update the dns over at namecheap to point to dh.,,
