They are transport protocols that run over IP links, and they define two different ways to send data from one point to another over an IP network path. TCP running over IP is written TCP/IP; UDP in ...

(In fact, it can't use TCP at all.) UDP isn't available with protocols such as IKEv2, L2TP, SSTP or PPTP. If you do see a UDP option, and it's not available by default, just try it. Flip the ...

TCP is one of those protocol, and it can run on top of IP datagrams (as is done typically) or UDP datagrams, in the case of applications like MixApp that don't want to use the operating system's ...

Google's QUIC, which stands for Quick UDP Internet Connection, obviously espouses the latter, but not for those usual cases but for things that use TCP/IP normally. That means, things like simply ...

If you have permitted both TCP and UDP port 53 to traverse to and from your DNS servers and are still not having any luck, you may have an issue with your DNS implementation.

According to this group, starting with February 1, 2020, DNS servers that can't handle DNS queries over both UDP and TCP may be pushed out of the DNS ecosystem and stop working.

The Transmission Control Protocol (TCP) is a more reliable transport layer protocol, albeit not as fast as UDP, that establishes a connection between systems only after an automated verification ...
