3.4 Flashcards
When private devices need access to other networks or the Internet a public facing gateway substitutes the private IP address is used by computers on the private network with it on public IP address this process is called
Network address translation
 This translation method assigns a separate TCP port to each session between a local host in the Internet host
Port address translation
Using this variation of network address translation the gateway assigns the same public IP address to a host each time it makes a request to access the Internet.
Small home networks with only a single public IP address provided by its ISP use this translation method
Source network address translation
Using this translation medicine host outside the network address a computer inside the Netwerk by predefined public IP address
Destination network address translation
The various servers can use – – – – – – – addresses for security and also to allow network administrators more freedom to manage the servers
Private IP
The __________addressing range created to handle the shortcoming of IPV four addresses mainly being the limited number of addresses the IP V4 address in scheme to provide
Ipv6
The IPV six address has 128 bits that are written as eight blocks of – – – – – – – separated by colons
Hexadecimal numbers
Each block in the IPV six address in scheme is – – – bit long
16
Shorthand and IPV six addressing makes them easier to handle this means any consecutive blocks with four zeros in it can be _________
Compacted
Hey – – – – sometimes called a local link is any land bounded by routers
Link
– – – – – – – Or two or more nodes on the same link
Neighbors
What network is configured to use both IPV for an IPv6 protocols the network is said to be – – – – –
Dual stacked
If package on the network much traverse over the net work where duel stacking is not use the solution is to use – – – – – – which is a method of transporting IPv6 package over IP V4 Netwerk
Tunneling
This specifies a single note on the net work
Unicast address
Can be routed on the Internet and is similar to public IPV four addresses most begin with the prefix 2000::/3 all the other prefixes are being released
Global address
