from a mail server.   
IMAP is the protocol that IMAP clients use to communicate with the servers, and SMTP is the protocol used to 
transport mail to an IMAP server. 
The current version of the Internet Message Access Protocol is IMAP4. It is similar to Post Office Protocol version 3 
(POP3), but offers additional and more complex features. For example, the IMAP4 protocol leaves your email 
messages on the server rather than downloading them to your computer. If you wish to remove your messages from 
the server, you must use your mail client to generate local folders, copy messages to your local hard drive, and then 
delete and expunge the messages from the server. 
IP   
IP is an acronym for Internet Protocol. It is a protocol used for communicating data across a internet network.   
IP is a "best effort" system, which means that no packet of information sent over it is assured to reach its destination in 
the same condition it was sent. Each device connected to a Local Area Network (LAN) or Wide Area Network (WAN) is 
given an Internet Protocol address, and this IP address is used to identify the device uniquely among all other devices 
connected to the extended network. 
The current version of the Internet protocol is IPv4, which has 32-bits Internet Protocol addresses allowing for in 
excess of four billion unique addresses. This number is reduced drastically by the practice of webmasters taking 
addresses in large blocks, the bulk of which remain unused. There is a rather substantial movement to adopt a new 
version of the Internet Protocol, IPv6, which would have 128-bits Internet Protocol addresses. This number can be 
represented roughly by a three with thirty-nine zeroes after it. However, IPv4 is still the protocol of choice for most of 
the Internet. 
IPMC   
IPMC is an acronym for IP MultiCast.   
IP Source Guard 
IP Source Guard is a secure feature used to restrict IP traffic on DHCP snooping untrusted ports by filtering traffic 
based on the DHCP Snooping Table or manually configured IP Source Bindings. It helps prevent IP spoofing attacks 
when a host tries to spoof and use the IP address of another host.
