What is the function of network masking?

A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs. To better understand how IP addresses and subnet masks work, look at an IP address and see how it’s organized.

What is a 25 subnet mask?

/25 — 2 Subnets — 126 Hosts / Subnet Network # IP Range. Broadcast. .0. .1 – .126.

Why does Cisco use wildcard masks?

Wildcard masks are used to specify a range of network addresses. They are commonly used with routing protocols (like OSPF) and access lists. Just like a subnet mask, a wildcard mask is 32 bits long.

What is the use of 0.0 0.0 IP address?

IP address 0.0. 0.0 is used on servers to designate a service may bind to all network interfaces. It tells a server to “listen” for and accept connections from any IP address. On PCs and client devices.

Why does a ping send 4 packets?

In order to verify a computer’s availability, ping sends in its default setting four ICMP echo request packets of 32 bytes each to the address assigned as a parameter. ICMP (Internet Control Message Protocol) is a protocol that enables the exchange of information and error notifications within IPv4 networks.

Why is subnet 255?

A subnet mask is a 32-bit number created by setting host bits to all 0s and setting network bits to all 1s. In this way, the subnet mask separates the IP address into the network and host addresses. The “255” address is always assigned to a broadcast address, and the “0” address is always assigned to a network address.
