E-mail protocols [edit]. The Internet Message Access Protocol is an Application Layer Internet protocol that allows an e-mail client to access e-mail on a remote mail server. The current version, IMAP version 4 revision 1 (IMAP4rev1), is defined by RFC 3501. An IMAP server typically listens on well-known port 143.
APIPA is short for Automatic Private IP Addressing, a feature of later Windows operating systems, meant for non-routed small business environments, usually less than 25 clients. With APIPA, DHCP clients can automatically self-configure an IP address and subnet mask when a DHCP server isn't available.
