There aren't any Dunmer "strongholds" in Skyrim. However, you may come across a Bandit camp or fort with a high number of Dunmer bandits, but they'd be there randomly and not scripted to be there. There is the Grey Quarter in Windhelm that houses several Dunmer. If your post has to do with the quest Discerning the Transmundane this page will help. Hope this helped!

P.S.

If you get the Dragonborn DLC, the island of Solstheim has a whole town/city of Dunmer occupants.
