Electronic device with cover that identifies it on the net (2,7)

I believe the answer is:

ip address

I'm a little stuck... Click here to teach me more about this clue!

'electronic device' is the definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?

'cover that identifies it on the net' is the wordplay.
I cannot really see how this works, but
'cover' could be 'address' (synonyms) and 'address' is located in the answer.
This may be the basis of the clue (or it may be nonsense).

'with' is the link.

Can you help me to learn more?

I've seen this clue in The Irish Times.
