There aint no dedicated servers for COD after black ops 1, now all COD titles uses 'listen servers' for most of their future titles under this game franchise hence the lag we often experience in mp.

“Advanced Warfare employs game servers hosted at data centers globally on all platforms and listen servers as part of our proprietary matchmaking system. Our goal is to ensure the best possible connection and greatest gameplay experience regardless of location and time of day.”

Let’s quickly recap the two kinds of servers that online video games typically employ. Most online games on Xbox 360 and PlayStation 3 used what Activision calls “listen servers.” This is when a game like Call of Duty hosts the online match on one of the player’s systems. Listen servers often experience lag because the connection is going over a residential line. The host also has an advantage since their “ping” is essentially zero.
