Using the output below: IP Address: 172.25.1.39 Subnet Mask: 255.255.255.0 Router: 172.25.1.252 Name Server: 172.25.1.4 Which of the following is the default gateway?

Rationale

172.25.1.252 is the default gateway.

The default gateway is the IP address of the router that forwards traffic from a local network to other networks, including the internet. In this case, the router's IP address, 172.25.1.252, serves as the default gateway for the specified IP configuration.

A (172.25.1.252) CORRECT

This is the correct choice as it represents the router's IP address, which functions as the default gateway for devices on the local network. The default gateway is responsible for routing traffic that is destined for networks outside the local subnet.

B (172.25.1.39) YOUR ANSWER

This address is the IP address assigned to the device on the network, not the gateway. While it allows the device to communicate within the local subnet, it does not serve the role of directing traffic to other networks, which is the primary function of a default gateway.

C (172.25.1.4) YOUR ANSWER

This address corresponds to the name server, which is used for resolving domain names to IP addresses. While important for network functionality, it does not perform the routing functions associated with a default gateway.

D (255.255.255.0) YOUR ANSWER

This is a subnet mask, which is used to define the network portion of an IP address. It indicates which part of the address is used for the network and which part is used for hosts. It has no role in routing traffic and therefore cannot be considered a default gateway.

Conclusion

The default gateway in a network configuration is critical for facilitating communication beyond the local subnet. In this scenario, 172.25.1.252 serves as the router's IP address, fulfilling the role of the default gateway. The other options represent either a device's IP address, a name server, or a subnet mask, none of which are responsible for routing traffic outside the local network.

Using the output below: IP Address: 172.25.1.39 Subnet Mask: 255.255.255.0 Router: 172.25.1.252 Name Server: 172.25.1.4 Which of the following is the default gateway?

172.25.1.252 is the default gateway.
