DNS (Domain Name Service) is used for domain name resolution.
There are some attacks that target vulnerabilities within DNS servers. Some trojans also use this port: ADM worm, li0n, MscanWorm, MuSka52, Trojan.Esteem.C (05.12.2005), W32.Spybot.ABDO (12.12.2005).
W32.Dasher.B (12.16.2005) - a worm that exploits the MS Distributed Transaction Coordinator Remote exploit (MS Security Bulletin MS05-051).
Listens for remote commands on port 53/tcp. Connects to an FTP server on port 21211/tcp. Scans for systems vulnerable to the MS05-051 exploit on port 1025/tcp.
Xbox LIVE uses ports 53 tcp/udp, 80 tcp, 88 udp, 3074 tcp/udp. |

TCP ports use the Transmission Control Protocol. TCP is one of the main protocols in
TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts
to establish a connection and exchange streams of data. TCP guarantees delivery of data
and that packets will be delivered in the same order in which they were sent.
Guaranteed communication is the key difference between TCP and UDP.
UDP ports use the Datagram Protocol, a communications protocol for the Internet network,
transport, and session layers. Like TCP (Transmission Control Protocol),
UDP is used with IP (the Internet Protocol) and makes possible the transmission of datagrams
from one computer to applications on another computer, but unlike TCP, UDP is connectionless
and does not guarantee reliable communication; it's up to the application that received
the message to process any errors and verify correct delivery.
