What is dns protocol?
DNS protocol was created to convert human domain names into IP address (intenet operates on IP addreses).
Which of the folllowing uses a single public IP address to access the Internet on behalf of all of the hosts on the network that may be using other IP addresses or private IP addresses?
•If the hosts on a network using private IP addresses need to access the Internet, a problem arises because the private IP addresses are not allowed on the Internet. •The solution is to use NAT (Network Address Translation), which uses a single public IP address to access the Internet on behalf of all hosts on the network using other IP addresses.
What are the main differences between the public and private network settings?
Public network is where the networked computers are not all trusted. Private network is where all computers are trusted. EG. Public network: cyber cafe. EG Private network: Your work or home network.
What IP addresses are not assigned to any specific user or organization instead they can be used by any user on the private internal network?
Private IP addresses
Which type of internet protocal address is 192.168.88.207?
192.168.x.x is an IP address in the private IP address range.
What uses a single public IP address to access the Internet on behalf of all of the hosts on the network that may be using other IP addresses or private IP?
NAT - Network Address Translation.
Is this an ip address 127.16.0.0?
172.16.0.0 is itself a private IP address. (IP addresses from 172.16.0.0 to 172. 31.255.255 are all private IP addresses. Other private IP addresses are 10.X.X.X and 192.168.X.X where X can be from 0 to 255). But it's not usable as an IP address for a device such as a PC or host. This is because it's the first address and, by convention, the first address of a network is used to indicate its network address.
Describe the difference between public and private IPv4 addresses. If a network is using private IP addresses how can the computers on that network access the Internet?
If a network is using a public IP address, anyone can use it to log on to the network. A private IP address requires a specific password. Only users who have the password can use that connection.
Which IP address processes enables workstations to use private IP addresses to access the Internet?
NAT (Network Address Translation) A service that translates a private IP address to a public IP address in packets destined for the internet, then translates the public IP address in the reply to the private address.
How can you find out the IPv4 of your network?
scan private ip ranges using network scan tool like solarwinds
When a PC reports it has used an automatic private IP address what can you assume about the network configuration and current connectivity?
You can assume that there is no connectivity from the PC to the network and that the PC is on it's own private network.
What is the difference between private IP addresses and public IP addresses?
public ip-addresses are used in the Internet (they are registered addresses). private ip-addresses are used in local networks. imagine you have a computer in your local network that has a public ip-address and your PC has simultaneously an Internet connection: if you try to ping this pc you wouldn't be able to tell which computer is replying, the local one or the webserver.
