What's a private IP
address?
·
An IP address that
doesn't connect to the internet on an internal network, given by NAT (Network
Address Translation) and are on the class c range.
What's a public IP
address?
·
An IP address that connects
to the internet
What's a static IP
address?
·
An IP address that
doesn't change
What's a dynamic IP
address?
·
An IP address that
changes and is assigned by the network when they connect.
What's APIPA's network
number?
·
169.254.0.0
What's APIPA?
·
Automatic Private IP
Address, used if a client can't get an address from DHCP server and doesn't
have one, it gives it an address.
What's NAT?
·
a method of remapping
one IP address into another by changing network address info in IP packet
headers while they are moving across a traffic routing device.
Why was NAT developed?
·
To slow the shortage
of IPv4 addresses
What is a default
gateway?
·
gives a default road
for TCP/IP hosts to use when talking to other hosts on remote networks
What's an example of
using a default gateway?
·
If your computer tries
to go to a website, it goes through your default gateway before leaving your
network and going to the internet
What's a DNS server?
·
A server that matches
up the name of a site to its ip address
What's an example of a
DNS server being used?
·
When you try to go to
Bing and the dns server grabs the IP address and takes you to that site.
What's CIDR?
·
It allows a network to
be divided into different-sized subnets to make one IP network
How many bits are in
IPv6?
·
128
What is VLSM?
·
allows a network to be
divided into different-sized subnets to make one IP network, so that they dont
waste IP addresses
What is a Dual IP
stack?
·
When you use both IPv4
and IPv6 at the same time
