'macOS zsh terminal $HOST displays .ht.home

I've been tinkering with my .zshrc file for a while to change how the command prompt looks and also make it display certain statuses for git. But after I made some changes when I type in echo $HOST to see the hostname of my laptop, this shows up. (narnia is just what I named the hostname) It used to show narnia.local, but now it shows narnia.ht.home. Could someone explain what caused this to change, and whether or not it's something I should worry about?
