It's a logical address.

Physical addresses are the actual spots in memory. Logical addresses are a set of pretend addresses assigned to each process that are mapped into physical addresses by the OS when the process is loaded. The benefit of logical addresses is that an executable can refer to specific addresses for things such as entry points and jumps without worrying about those addresses being unavailable at runtime. They're always available because they're not real.
