And if the plane has no name? Then it would give it's location. For example, a Genesis spawned demi-plane would be identified by its location in the Ethereal Plane.
the spell reveals the name of the creature or object’s location (place, name, business name, building name, or the like), community, county (or similar political division), country, continent, and the plane of existence where the target lies.
Would it?
-The spell doesn't say you "identify the location" only that you get some names. So if the plane has no name, bad luck.
-If someone is in a Genesis plane, and it has a name, then you learn the name of the Genesis plane. The Genesis plane isn't inside the Ethereal plane, it just borders with it.
Even if it was part of the Ethereal Plane, then you would still learn either that the target is on the "Ethereal plane", or that the target is on the "Genesis plane". Because you get only 1 name for "plane of existence where the target lies".
So the unnamed plane from the Rope Trick could only be identified by its location. Except it has no location, other than the position of the only portal to it.
Discern location doesn't "identify" the location of the target...it just tells its name.If it hasn't a name, it can't do something extra to explain what plane is that.
Now I suppose the caster could name his Rope Trick plane, but it would be up to the DM to decide if simply applying a personal label, known to nobody else, is in any way meaningful.
Think of it this way, you're on a ship called the Pequod. But you like to think of it as the Amnesia. You're in the Sea of Swords, but you like to think of it as the Stormy Sea.
What names would a Discern Location provide? Obviously, the names these are actually known by, so if you give a very temporary plane a name, and it isn't actually known by that name to anyone outside it, the only person you're likely to fool is yourself.
Obviously? Nope, I would say its up to luck what name discern location will provide. Except if in-game there is somewhere a book that states the legal names for every location possible for the purposes of discern location. I don't think it is possible for such a book to exist out-of-game however.
If it works with "how most ppl would name that thing" then the rope trick is just named "Rope Trick ". You don't get to name it "Plane next to the x wall in x dungeon" because 1) You don't decide its name as a minority 2) Even if you did, you don't know its location. 3) Even if the creator was smart enough to call it "Plane next to the x wall in x dungeon" it still wouldn't be named like that, because most ppl call those things "Rope Tricks".

Also, it looks like that standing or sitting works as a measure to prevent Discern Location.
Yeah I know some of you will argue that this only blocks the name of the plane of existence.
