You don't need to make it complicated by getting packet tracing software.
What Operating System are you using?
ipconfig will still show your IP address even if it is static.
Wireshark is for network administrators really. Not needed to find a nodes address or gateway. I would be fired from my job (I work in IT) if I told my boss I am running Wireshark to find a my nodes IP address.
Your IP address will be displayed like this if using Windows (I am using a static IP):
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::fdbf:e50e:fae:1ef4%11
IPv4 Address. . . . . . . . . . . : 192.168.1.100
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1
A preferred address is an address that has been assigned to an interface and that can be used without any restrictions. So it has nothing to do with static vs dynamic IP addresses.
Typing ipconfig /all yields the (preferred address) which just signifies it is uniqueness on the network. This can be in an "Invalid" and "Tentative" state by the lease of you DHCP address is expired or being verified. I hope that helps. Let me know if I should clarify further
