11 What’s reported by the ipconfig command for each connection?
On LAN 2 – PCI Card, DHCP is not enabled. A manual IPv4 address, along with a
subnet mask, default gateway, and DNS server address are reported. There is no
IPv6 information, as you disabled IPv6 on this NIC.
On Local Area Connection, DHCP is enabled. You have an IPv6 link-local address
(meaning the IPv6 address was self-configured, similar to an IPv4 APIPA address).
The IPv4 address, subnet mask, default gateway, DHCP and DNS server
addresses are reported, along with details regarding your IP lease—when it was
obtained and when it expires.
17 Which TCP/IP configuration parameters are configured for distribution
to clients with an IPv4 address lease?
Router, DNS Server, and DNS Domain Name
19 If you had added a WINS server to your network, which value would
you configure in the Server Options box?
044 WINS.NBNS Servers
