4b) The computer utilizes a wired Ethernet connection. The network adapter is identified by the physical or mac address 00-50-B6-62-2A-2C. The connection’s IPv4 address, 192.168.0.136, was assigned through DHCP by a server at 192.168.0.1. The Internet gateway and DNS proxy are also 192.168.0.1 indicating this is likely an all-in-one router. The connection’s external IPv6 address is 2605:6000:1007:c040:c1f1:92a7:bfbb:dfdb and is changed once a day to avoid address tracking. The connection’s local IPv6 address is fe80::f43f:aa49:2b7b:5698 and was assigned by the router.
