What is IP?
It's a unique 32 bits
software address of a node in a network.
What is private IP?
Three ranges of IP
addresses have been reserved for private address and they are not valid for use
on the Internet. If you want to access internet with these address you must
have to use proxy server or NAT server (on normal cases the role of proxy
server is played by your ISP.).If you do decide to implement a private IP
address range, you can use IP addresses from any of the following classes:
Class A 10.0.0.0 10.255.255.255
Class B 172.16.0.0 172.31.255.255
Class C 192.16.8.0.0 192.168.255.255
Class A 10.0.0.0 10.255.255.255
Class B 172.16.0.0 172.31.255.255

What are the
differences between static ip addressing and dynamic ip addressing?
With static IP
addressing, a computer (or other device) is configured to always use the same
IP address. With dynamic addressing, the IP address can change periodically and
is managed by a centralized network service
What is APIPA?
Automatic private IP
addressing (APIPA) is a feature mainly found in Microsoft operating systems.
APIPA enables clients to still communicate with other computers on the same
network segment until an IP address can be obtained from a DHCP server,
allowing the machine to fully participate on the network. The range of these IP
address are the 169.254.0.1 to 169.254.255.254 with a default Class B subnet
mask of 255.255.0.0.
What are the LMHOSTS
files?
The LMHOSTS file is a
static method of resolving NetBIOS names to IP addresses in the same way that
the HOSTS file is a static method of resolving domain names into IP addresses.
An LMHOSTS file is a text file that maps NetBIOS names to IP addresses; it must
be manually configured and updated.
What is DHCP scope?
A scope is a range, or
pool, of IP addresses that can be leased to DHCP clients on a given subnet.
What is FQDN?
An FQDN contains
(fully qualified domain name) both the hostname and a domain name. It uniquely
identifies a host within a DNS hierarchy
What is the DNS
forwarder?
DNS servers often must
communicate with DNS servers outside of the local network. A forwarder is an
entry that is used when a DNS server receives DNS queries that it cannot
resolve locally. It then forwards those requests to external DNS servers for
resolution.
Which command will you
use to find out the name of the pc in networks?
