ISATAP and TEREDO

Name two tunneling protocols that are used for IPv6 packets to travel over an IPv4 network.

Port 25

At what port does an SMTP email server listen to receive email from a client computer?

Public IP addresses are licensed and authorized to use the internet. Private IP addresses are not authorized or licensed to use the internet. A computer with a private IP address uses a NAT router to access the internet.

Describe the difference between public and private IPv4 addresses. if a network. If a network is using private IP addresses, how can the computers on that network access the internet?

By a port number.

How does a client application identify a server application on another computer on the network?

IP addresses that begins with 2000+ are global addresses used on the internet. Addresses that begin with FE80+ are link local addresses used on a private network.

How is an IPv6 address used that begins with 2000...? that begins with FE80?

There are 48 bits.

How many bits are in a Mac address?

There are 32 bits in an IPv4 IP address, and 128 bits in an IPv6 IP address.

How many bits are in an IPv4 IP Address? In an IPv6 IP address?

The subnet ID block contains 16 bits bits. the value of these bits for a link local address are 0000 0000 0000 0000.

How many bits are in the subnet ID block? what are the values of these bits for a link-local IP address?

Automatic private IP address (APIPA)

If no DHCP server is available when a computer configured for dynamic IP addressing connects to the network, what type of IPv4 address is assigned to the computer?

Private IP addresses.

What are IP addresses called that begin with 10, 172.16, or 192.168?

the interface ID which is used uniquely identify the network connection on the local link.

What the last 64 bits of an IPv6 address called? how are these bits used?

Remote desktop and Remote Assistance

What two windows applications use the RDP protocol and port 3389?

SSH

What type of encryption protocol does secure FTP (SFTP) use to secure FTP Transmissions?

DNS server

What type of server resolves fully qualified domain names to IP addresses?

TCP, UDP

Which TCP/IP protocaol that manages packet delivery guarantees that delivery? which protocol does not guarantee delivery, but is faster?

LDAP

Which protocol is used when an application queries a database on a corporate network such as a database of printers?

HTTPS uses either HTTP together with SSL or TLS encryption protocols

Which protocol(s) does a web server use when transmissions are encrypted for security?

IP addresses that begin with 192.168 are private IP addresses.

Why is it unlikely that you will find the IP address 192.168.250.10 on the internet?

The IP address was automatically assigned by windows when it failed to lease an address from the DHCP server. the computer received an APIPA IP address.

if a computer is found to have an IP address of 169.254.1.1, what can you assume about how it received that IP address?

DHCP server

what type of server serves up IP addresses to computers on a network?

NAT

what type of technology is used to present a public IP address to computers outside the LAN to handle requests to use the internet from computers inside the LAN?

IMAP

which email protocol allows a client application to manage email stored on an email server?

unique local addresses

which type of IPv6 address is used to create multiple subnets within a large organization?
