What option would you specify after the ipconfig command to display the IP address of a Windows PC's DNS server? a.

Static ARP entries tend to be more problematic than dynamic entries. 2. ipconfig commands can be used to release and renew an DHCP lease for IPv4. 3. ipconfig /all will display information about DNS server's IP address and the computer's MAC address. 4. When you issue ipconfig on a computer with two NICs, it will display information about all IP addresses attached to both NIC. 5. netstat lists source and destination IP addresses and port numbers for all open IP-based sessions. 6. ping command use ICMP protocol. 7. nslookup, host, and dig all are commands that can be used to resolve an IP address of a domain name. 8. The UNIX ifconfig command is most similar to the Windows ipconfig 9. The UNIX netstat command serves the same basic purpose of the Windows netstat command. 10. unlike the Windows ping command, the UNIX ping command sends continuous pings
