What could this pipe be connected to?
I have a two story home, built in 2003, with a small covered back porch (about 8x10) sticking off the back of the home. Just outside and above of the backdoor, there is a small pipe protruding down from the ceiling of the porch. It is about 1 1/2" in diameter, and is sticking out about 3-4". I've never known what it does before, but this morning it is dripping water. It has never done this before, it did not rain last night, and I can't see anything on the roof above it to indicate what it might be draining. Any clues? We have had some water damage from various leaking appliances lately, so now I am afraid of any unknown water source!
If it helps, the layout of the house is that there are two bedrooms along the south (backyard) wall upstairs, and a bathroom and laundry room along the east. We have a heat pump, and the furnace unit is also located centrally upstairs.

That pipe is there to let you know you may have a problem,.... The HVAC unit (heat pump operates as an ordinary air conditioner in the summer) has a condensate drain that is supposed to drain to a place you wouldn't notice so some of the newer construction methods have been to plumb the main drain to the house plumbing.
The problem arises when that drain has clogged. The HVAC unit, just like the water heater has a secondary drain pan. THAT pan has a drain that is piped to the exterior of the house, and if you see water coming from it, its time to act. Now. Get qualified service personnel out there first thing in the morning!

This is possibly an overflow pipe from the a/c unit. Units that are located above areas where damage could occur from drain lines that are plugged have safety pans underneath the unit and those pans would have a drain line that would be piped to a location that is visible to the homeowner to alert them that there is a problem that needs attention.If this is the case it needs to be corrected.

A/C condensate drain. You probably didnt notice it before because it has been winter and you have been running your heat all winter.

It is an overflow pipe for an appliance, bathroom etc.

Sounds to me like the AC drainage.
