Last year I bought the domain "EzraHarris.com" and still use it for my main blog to this day, but recently I thought that my second blog (this one Ezra Codes.) had a pretty lengthy URL, which by default Posthaven gives you a subdomain like for an example: yourblog.posthaven.com. so I thought instead of buying a whole new domain for my second blog why not use my current domain but add a subdomain, I went to GoDaddy and went to the "Manage DNS" on my domain and added an "A" record to the list with the name being: "coding" and then added the "Points To:" value to the given IP which posthaven gives you when adding a custom domain. Then I went back to Posthaven and changed the URL to "Custom Domain" and put "coding.EzraHarris.com" into the field. So now the domain for this blog is coding.ezraharris.com, although you can still access the site via the domain "ezracodes.posthaven.com" as a backup if the other domain fails. I learned this from my brother Nicholas last year when I set up my own Minecraft server and I wanted to use Play.Ezraharris.com instead of my IP (for safety reasons.)
