Module 6: IPv4 address structure
Which full range of decimal values are valid in one octet of an IPv4 address?
0 through 255
How many octets exist in an IPv4 address?
4
What do devices on the same IPv4 subnet have in common?
They all use the same default gateway.
What is the prefix length notation for the subnet mask 255.255.255.224?
/27
Which is a valid default gateway address for a host configured with IP address 10.25.1.110 and a subnet mask of 255.255.255.192?
10.25.1.65
Host-A has the IPv4 address and subnet mask 10.5.4.100 255.255.255.0. What is the network address of Host-A?
10.5.4.0
How many unique addresses are available for assignment to hosts in the network of 10.100.16.0 with subnet mask 255.255.252.0?
1022 - See image
Host-A has the IPv4 address and subnet mask 172.16.4.100 255.255.0.0. What is the network address of Host-A?
172.16.0.0
What is obtained when ANDing the address 192.168.65.3/18 with its subnet mask?
192.168.64.0 - See image
For what purpose are IPv4 addresses utilized?
An IPv4 address is used to uniquely identify a device on an IP network.
Which statement describes one purpose of the subnet mask setting for a host?
It is used to determine to which network the host is connected.
Which statement describes IPv4 addressing?
Routers use the full 32-bit IP address to determine the location of each individual host. The network portion of a destination IP address is obtained by performing an AND operation between a host IP address and a subnet mask.
