ASA Active / Standby, can I recycle the inside interface of the Standby

Futura

So I got myself a couple of 5525x ASAs,

Configured inside and outside interfaces, the usual stuff.

Connected them together with xovers and set up failover. All fine,.

So now, the secondary is a duplicate of the primary. agreed?

Does that mean I can reuse the IP address I originally set to the inside interface of the secondary? or should I keep it free and available. I'm not short on addresses by the way. I'm just curious.

Many thanks:)

I'm no security guru, but the way we have it setup is the secondary inside int has it's own IP assigned. In an event of a failover, the secondary assumes the primarys inside IP and traffic flows without incident.
