This the default subnet mask for the apipa address gateway blank

Lab Report: 5.8.5 Explore IP Configuration
Explanation
In this lab, you should have completed the following:
DHCP Enabled: No. This tells us that the Server is configured with a static IP address and is not enabled for DHCP
IPv4 Address: 192.168.0.10
In the Executive Office, the link and network activity lights on the back of the workstation are on and blinking, indicating that there is a physical connection to the switch and there is activity on the connection. This points to a TCP/IP configuration problem.
On the Executive Office workstation (Exec), the network icon in the notification area has a yellow warning sign with an exclamation point which indicates a connection to the local network, but no access to the Internet. When you click the network icon, you see the details of this status. The Network and Sharing Center diagram confirms that Exec is connected to the local network, but has no Internet access.
Subnet Mask: 255.255.255.240
Default Gateway: 192.168.0.4
subnet mask for the Class C IP address range being used. With 255.255.255.240 as a subnet mask, the network would only include addresses from 192.168.0.48 to 192.168.0.63. The IP address for CorpServer (192.168.0.10) and the ISP fall outside of this range. The information in step 4 confirms that the default subnet mask for the Class C IP address range (255.255.255.0) is being used.
After correcting the subnet mask on Exec, there are still no changes to the network icon or to the diagram in the Network and Sharing Center.
After configuring the correct gateway address on Exec, the network icon and the diagram in the Network and Sharing Center confirm that Exec is connected to the Internet.
Using the tracert command again returns a path to the ISP through the gateway. Since we have a valid connection to the Internet, we will leave the static address for now while we troubleshoot in Office 1.
DHCP Enabled: Yes. This tells us that the workstation is configured to use a DHCP server.
IPv4 Address: This address is in the APIPA range (169.254.0.1 to 169.254.255.254). This means that the workstation assigned itself an IP address instead of receiving one from the DHCP server. The workstation will only be able to communicate with other hosts on the local network that have also configured their own IP address through APIPA.
On CorpDHCP12, launch the DHCP console and activate the scope.
On Office1, the ipconfig /renew command will request new IP address information from the DHCP server, and it will reconfigure the settings for the Local Area Connection.
On CorpDHCP12, launch the DHCP console and reconfigure the settings for the DHCP scope.
On Office1, the ipconfig /renew command will request new IP address information from the DHCP server, andit will reconfigure the settings for the Local Area Connection.
The ipconfig /all command now shows the IP address, Default Gateway, DNS Server, DHCP Server that wereprovided by the DHCP server.
The network icon and the diagram in the Network and Sharing Center indicate that Exec is connected to thecorporate network with full Internet access.
