I would like to know if a hostname is a valid value for *Endpoint*? Today,

Today, Mullvad <https://mullvad.net/en/> currently sets *EndPoint* to a
hostname (see here <https://api.mullvad.net/public/relays/wireguard/v1/>)
In my case, my host is set to use a DNS server which routes VPN provider
domains to a bad IP (in order to block them).
1. If *EndPoint* should never be a hostname, perhaps we should prevent (or

2. If *EndPoint* can be a hostname, then I think we want to ensure DNS is
set from the configuration file before attempting to connect. In the wg-quick
I updated the *cmd_up()* function to call *set_dns()* earlier on than it is
currently called. This prevents my host's original DNS server from blocking
