| CIFS | A file access protocol and the cross-platform version of SMB used between Windows, Linux, macOS, and other operating systems. |
| CNAME record | a DNS record that redirects from one host name to another. |
| connection-oriented protocol | In networking, a TCP/IP protocol that confirms a good connection has been made before transmitting data to the other end, verifies that data was received, and resends data if it was not received. |
| DHCP | Protocol used to assign a dynamic IP address to computers when they first attempts to initiate a connection to the network and requests and IP address. |
| DKIM record | a txt-type DNS record that authenticates an email message from a trusted source by attaching a domain name identifier to the message |
| DMARC record | a txt-type DNS record that tells a recipient’s mail server what to do when it receives a fraudulent email message. |

| Link | In TCP/IP version 6, a local area network or wide area network bounded by routers. Also called local link. |
| link local address | An IP address that is automatically assigned by an operating system to allow a node to communicate over its local subnet if a routable IP address is not available. |
| loopback address | An IP address that indicates your own computer and is used to test TCP/IP configuration on the computer. |
| MAC address | a 48-bit (6-byte) identification number that is hard-coded on the card by its manufacturer and identifies a network adapter. |
| multicast address | In TCP/IP version 6, an IP address used when packets are delivered to a group of nodes on a network. |
