NAT Types
What automatically maps internal IP addresses with a dynamic port assignment?
Dynamic NAT
What class is this?
192.168.16.10
Class C
This implementation is also sometimes called many-to-one NAT because many internal private IP address are mapped to one public IP address on the NAT router.
Dynamic NAT
Which device is NAT typically implemented on?
Default gateway router
What allows you to connect a private network to the internet without obtaining registered addresses for every host?
Network Address Translation (NAT)
What are these IP Addresses?
10.0.0.1 to 10.255.255.254
172.16.0.1 to 172.31.255.254
192.168.0.1 to 192.168.255.254
Private IP Addresses
When connecting a private network to the internet through NAT, IP addresses on the private network are commonly those reserved by the Internet Assigned Numbers Authority (IANA)?
Reserved Private IP Addresses
A method that allows you to connect a private network to the internet without obtaining registered addresses for every host?
NAT
What maps a single private IP address to a single public IP address on the NAT router?
Static NAT
What do hosts on a private network share if the network utilizes a NAT router?
Physical IP address
A 32-bit numerical addressing method. It contains 12 header fields and checksum fields, supports broadcast and variable length subnet masking, and uses ARP.
IPv4 (Internet Protocol version 4)
Allows incoming traffic addressed to a specific port to move through the firewall and be transparently forwarded to a specific host on the private network?
DNAT
Assigns 2 IP addresses to the public NAT interface.
Dynamic and Static NAT
What class is this?
10.169.25.250
Class A
Port forwarding allows incoming traffic addressed to a specific port to move through the firewall and be transparently forwarded to a specific host on the private network.
Static NAT
What tables does a NAT router store port numbers and their associated private IP addresses?
Translation table
The NAT router keeps up with all translation requests so that it knows which hosts are requesting and receiving.
Port Address Translation (PAT)
What is not the right NAT IP address?
169.254.0.1 to 169.254.255.254
172.16.0.1 to 172.31.255.254
192.168.0.1 to 192.168.255.254
10.0.0.1 to 10.255.255.254
169.254.0.1 to 169.254.255.254
A 128-bit alphanumeric addressing method that contains 8 header fields and uses NDP. It does not contain checksum fields or support broadcast or variable length subnet mask.
IPv6 (Internet Protocol version 6)
What is true about Network Address Translation?
It supports up to 5,000 concurrent connections.
