MongoDB port is 65500 then which port use for HTTP rest?

Question

if Mongo server run on port 65500. Now on which port, I can access simple HTTP rest ? Let a case,

MongoDB provides a simple http interface listing information of interest to administrators. This interface may be accessed at the port with numeric value 1000 more than the configured mongod port.

if MongoDB runs on localhost with port number 65500. Then which port does Mongo rest interface run?

Port no. 66500 is not possible value for port

Answer 1

Port numbers are only 16 bits, so mongod will fail to even start on that port (greater than 65535)

> mongod --port 65555 --dbpath .

If you really mean an allowed port that would just make the web port go above 65536, it will wrap around to 0 (which would mean 65535+1000 would wrap to 999, or your new sample port 65500 would wrap to 964);
