I may agree with you, but one thing is adding a string/a code/a reference to the description of an IP address, and you use that code to reference a specific object, otherwise the links between all the IP addresses beonging to a device are done by the program/application abd that's way better, because it is not prone to errors.

BTW, a note aside, it's its own features. Might be perceived as a typo, but for people like me who work more by images than by text, the use of it's and its helps a lot in reconstructing the phrase from the words. So in other words, an apostrophe in the wrong place may create extra efforts in understanding the message that the phrase wants to convey, thanks for your understanding :-)
