We have just covered the most basics of networks, but, of course, there is almost a dozen of technologies, which are worth to look at. Google VXLAN on your own, learn TCP and UDP (and figure out which one when to use), look at IMCP. You will encounter new terms constantly, but, as always, the most important thing is to learn the fundamentals. Jul 17, 2020 · Application of UDP. UDP method is largely used by time-sensitive applications as well as by servers that answer small queries from a larger client base. UDP is compatible with packet broadcasts for sending all over the network and for multicasting sending. It is also used in Domain Name System, Voice over IP, and online games. Advantage of TCP Section 6.1.3.2 of [RFC1123] states: DNS resolvers and recursive servers MUST support UDP, and SHOULD support TCP, for sending (non-zone-transfer) queries. However, some implementors have taken the text quoted above to mean that TCP support is an optional feature of the DNS protocol. Feb 18, 2018 · By the end of this course, you’ll be able to: - describe computer networks in terms of a five-layer model. - understand all of the standard protocols involved with TCP/IP communications. - grasp TCP/IP - Transport Control Protocol/Internet Protocol. A set of rules for communication between computers where each device (host) is assigned a unique IP address which is valid on a particular network. An IP address is made up of 4 "octets" ranging between 0 and 255, and separated by a period or dot. (Ex. 128.241.171.241) DNS uses TCP when the size of the request or the response is greater than a single packet such as with responses that have many records or many IPv6 responses or most DNSSEC responses. The maximum size was originally 512 bytes but there is an extension to the DNS protocol that allows clients to indicate that they can handle UDP responses of up
DNS Encryption Explained Oct 29, 2019 Domain Name System - Wikipedia DNS primarily uses the User Datagram Protocol (UDP) on port number 53 to serve requests. DNS queries consist of a single UDP request from the client followed by a single UDP reply from the server. When the length of the answer exceeds 512 bytes and both client and server support EDNS , larger UDP …

What is UDP? | Cloudflare What is User Datagram Protocol (UDP/IP)? UDP is a communication protocol used across the Internet for especially time-sensitive transmissions such as video playback or DNS lookups. It speeds up communications by not requiring what’s known as a “handshake”, allowing data to be transferred before the receiving party agrees to the communication.
