When issuing “show ip nat translations” command, what five fields are given and what are they?

Pro- Protocol type
Inside global- displays an IP address that represents an inside host as seen by hosts on the outside network
Inside local- displays the IP address configured on a host on the local network
Outside local- displays the IP address of a host on the outside network as seen from a host on the inside network
Outside global- displays the IP address configured on a host on the outside network

Example:
pro inside global inside local outside local outside global
tcp 203.0.113.62: 10.1.7.7: 192.0.2.28 192.0.2.28

Host A: 10.1.7.7
Host B: 192.0.2.28
Router A inside: 10.1.7.1
Router A outside: 203.0.113.62
