It looks like Parler transferred their domain name to Epik (as a registrar), but are not currently using them for hosting.
As recently as a few days ago, Epik explicitly stated that they have no plans to host Parler (https://mynorthwest.com/2461882/sammamish-epik-parler/). That said, since the site is behind "ddos-guard.net," it's difficult to tell who their actual host is.
I saw a couple articles or so that said Epik was hosting it, but it is possible that those authors just saw that Epik was the registrar and confused that with being the host.
