PORT 20 TCP/UDP File Transfer Protocal (FTP) [data transfer] A standard network protocol used to transfer computer files from one host to another host over a TCP-based network, such as the Internet. |
|
PORT 21 |

|
PORT 22 |
PORT 22 TCP/UDP Secure Shell Host (SSH), secure log in, file transfers (scp, sftp) and port forwarding. A network protocol to allow remote login and other network services to operate securely over an unsecured network. |
|
PORT 23 |
PORT 23 TCP/UDP Telnet protocol—unencrypted text communications (DATA) Telnet provided access to a command-line interface (usually, of an operating system) on a remote host. Most network equipment and operating systems with a configuration (including systems based on Windows NT) |
|
PORT 25 |
PORT 25 TCP/UDP Simple Mail Transfer Protocol (SMTP), used for e-mail routing between mail servers Send and receive mail messages, user-level client mail applications typically use SMTP only for sending messages to a mail server for relaying. For receiving messages, client applications usually use either POP3 or IMAP. |
|
PORT 37 |
PORT 37 TCP/UDP Time Protocol |
|
PORT 43 |
PORT 43 TCP WHOIS is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system, but is also used for a wider range of other information. The protocol stores and delivers database content in a human-readable format |
|
PORT 53 |
PORT 53 TCP/UDP Domain Name System (DNS) Distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating authoritative name servers for each domain. |
|
PORT 67 |
PORT 67 TCP/UDP Bootstrap Protocol (BOOTP) server; also used by Dynamic Host Configuration Protocol (DHCP) |
|
PORT 68 |
PORT 68 TCP/UDP Bootstrap Protocol (BOOTP) client; also used by Dynamic Host Configuration Protocol (DHCP) |
|
PORT 80 |
PORT 80 TCP/SCTP Hyper Text Transfer Protocol (HTTP) An application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web. |
|
PORT 101 |
PORT 101 TCP/UDP NIC host name |
|
PORT 107 |
PORT 107 TCP/UDP Remote Telnet Service Protocol (RTSP) |
|
PORT 109 |
PORT 109 TCP/UDP Post Office Protocol v2 (POP2) An application-layer Internet standard protocol used by local e-mail clients to retrieve e-mail from a remote server over a TCP/IP connection. POP has been developed through several versions, with version 3 (POP3) being the last standard in common use before largely made obsolete by the more advanced IMAP. |
|
PORT 110 |
PORT 110 TCP/UDP Post Office Protocol v3 (POP3) An application-layer Internet standard protocol used by local e-mail clients to retrieve e-mail from a remote server over a TCP/IP connection. |
|
PORT 115 |
PORT 115 TCP Only Simple File Transfer Protocol (SFTP) |
|
PORT 118 |
PORT 118 TCP/UDP Structured Query Language (SQL) Services |
|
PORT 123 |
PORT 123 TCP/UDP Network Time Protocol (NTP), used for time synchronization |
|
PORT 137 |
PORT 137 (TCP/UDP) NetBIOS Name Service (NNS) Name service (NetBIOS-NS) for name registration and resolution. |
|
PORT 138 |
PORT 138 TCP/UDP NetBIOS Datagram Service (NDS) Distribution service (NetBIOS-DGM) for connectionless communication. |
|
PORT 139 |
PORT 139 TCP/UDP NetBIOS Session Service (NSS) Session Service (NetBIOS-SSN) for connection-oriented communication. |
|
PORT 143 |
Internet Message Access Protocol (IMAP) An Internet standard protocol used by e-mail clients to retrieve e-mail messages from a mail server over a TCP/IP connection. IMAP is defined by RFC 3501 |
|
PORT 153 |
PORT 153 UDP Simple Gateway Monitoring Protocol (SGMP) Allows commands to be issued to application protocol entities to set or retrieve values (integer or octet string types) for use in monitoring the gateways on which the application protocol entities reside. Messages are exchanged using UDP and utilize unreliable transport methods. Authentication takes place on UDP port 153. Interface Status, Route Type, Route protocol |
|
PORT 161 |
PORT 161 UDP Only Simple Network Management Protocol (SNMP) An Internet-standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks and more. |
|
PORT 162 |
PORT 162 TCP/UDP Simple Network Management Protocol Trap (SNMPTRAP) |
|
PORT 194 |
PORT 194 Internet Relay Chat (IRC) An application layer protocol that facilitates communication in the form of text. The chat process works on a client/server networking model. IRC clients are computer programs that a user can install on their system. These clients communicate with chat servers to transfer messages to other clients |
|
PORT 443 |
PORT 443 Hyper Text Transfer Protocol Secure (HTTPS) HTTPS signals the browser to use an added encryption layer of SSL/TLS to protect the traffic. |
|
PORT 264 |
PORT 264 TCP/UDP Border Gateway Multicast Protocol (BGMP) An IETF project which attempted to design a true inter-domain multicast routing protocol. BGMP was planned to be able to scale in order to operate in the global Internet. |
|
PORT 520 |

|
PORT 860 |
PORT 860 TCP (iSCSI) SCSI commands over IP networks, iSCSI is used to facilitate data transfers over intranets and to manage storage over long distances. iSCSI can be used to transmit data over LANs, WANs, or the Internet and can enable location-independent data storage and retrieval. It is a storage area network (SAN) protocol, allowing data center storage arrays while providing hosts (such as database and servers) with the illusion of locally attached disks. |
|
PORT 1512 |
PORT 1512 TCP/UDP Windows Internet Name Service (WINS) Effectively, WINS is to NetBIOS names what DNS is to domain names a central mapping of host names to network addresses. Like the DNS, it is implemented in two parts, a server service (that manages the embedded Jet Database, server to server replication, service requests, and conflicts) and a TCP/IP client component which manages the client's registration and renewal of names, and takes care of queries. |
