Memory Alpha is a Wikia wiki, but it was allowed to keep its original domain after it was acquired by Wikia following an initial period of independence. The user database structure also requires that you enter your Wikia credentials when visiting the site in order to be logged in there as well. Compare with the *.ffcixlopedia.org subdomains, or uncyclopedia—whose user database is entirely separate—or Wookieepedia, which still has wookieepedia.com pointing to it.
