IPv4 uses broadcast packets, while IPv6 does not
What is a broadcast domain?
A group of devices on the same network segment
What is the primary reason for the introduction of private IPv4 addresses?
To deal with the depletion of IPv4 address space
What is a characteristic of private IPv4 addresses?
They are not globally routable and can be used internally
What is the purpose of NAT in internal networks?
To translate private IPv4 addresses to public IPv4 addresses
What is the range of the private IPv4 address block 10.0.0.0/8?
10.0.0.0 - 10.255.255.255
What is the primary function of ISPs in terms of IPv4 addresses?
To globally route public IPv4 addresses between networks
What is the range of the private IPv4 address block 192.168.0.0/16?
192.168.0.0 - 192.168.255.255
What is the purpose of using public IPv4 addresses?
To enable global routing between ISP networks
What is the term for the process of translating private IPv4 addresses to public IPv4 addresses?
Network Address Translation
What is the purpose of variable-length subnet masking (VLSM)?
To minimize the number of unused host addresses per subnet
What is the primary difference between the intranet and the DMZ?
The intranet is accessible only within the organization, while the DMZ is accessible from the internet
What is the advantage of using private IPv4 addresses for intranet devices?
They can be used for any organization without restrictions
What is the result of subnetting an IPv4 network address space?
It divides the network into smaller subnets with more hosts
What is the purpose of subnetting on an octet boundary?
To make subnetting easier and more flexible
How many hosts can each of the 1000 subnets support?
16,382
What is the purpose of using a subnet mask of /16 or /24?
To subnet on an octet boundary
What is the benefit of using private IPv4 addresses for intranet devices?
They can be used for any organization without restrictions
What is the primary purpose of a DMZ in a computer network?
To separate a local area network from other untrusted networks
What is the primary consideration when planning subnets?
The number of subnets needed and the number of host addresses required for each network
What is the number of available subnets and hosts for a /25 subnet mask?
2 subnets, 126 hosts
What is the purpose of the subnet mask in determining the number of hosts and subnets?
To determine the number of hosts and subnets, and to separate the network and host portions of an IP address
What is the formula to calculate the usable number of addresses in a subnet?
2n – 2
What is the purpose of a network addressing scheme?
To accommodate the maximum number of hosts for each network
What is the number of bits left in the host portion that determines the number of hosts in a subnet?
The number of bits in the host portion
What is the purpose of a DMZ in terms of security?
To add an extra layer of security to the network
