  • Domain Name System 1 Domain Name System
    Domain Name System 1 Domain Name System The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. A Domain Name Service translates queries for domain names (which are easier to understand and utilize when accessing the internet) into IP addresses for the purpose of locating computer services and devices worldwide. An often-used analogy to explain the Domain Name System is that it serves as the phone book for the Internet by translating human-friendly computer hostnames into IP addresses. For example, the domain name www.example.com translates to the addresses 192.0.43.10 (IPv4) and 2620:0:2d0:200::10 (IPv6). The Domain Name System makes it possible to assign domain names to groups of Internet resources and users in a meaningful way, independent of each entity's physical location. Because of this, World Wide Web (WWW) hyperlinks and Internet contact information can remain consistent and constant even if the current Internet routing arrangements change or the participant uses a mobile device. Internet domain names are easier to remember than IP addresses such as 208.77.188.166 (IPv4) or 2001:db8:1f70::999:de8:7648:6e8 (IPv6). Users take advantage of this when they recite meaningful Uniform Resource Locators (URLs) and e-mail addresses without having to know how the computer actually locates them. The Domain Name System distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating authoritative name servers for each domain.

  • Design of a Reactive DNS Measurement System
    Design of a Reactive DNS Measurement System Jochem Braakhuis 13-07-2021, University of Twente [email protected] Abstract—For speed, robustness and safety of the Internet, it is will then delegate the query to the appropriate top-level domain important that information on name servers in every level of the name server dependent on the entered domain (.com, .org, .nl). hierarchical DNS structure is accurate and consistent. OpenIN- Then, the top-level domain name server will in turn delegate TEL, designed in 2016, measures about half of the global names- the query to the authoritative name server for the entered pace every day, but lacks flexibility in reactive measurement. To domain, which finally returns the IP address of the domain’s provide an easily scalable framework for performing research server to the user, or delegate it to authoritative name servers in DNS inconsistencies, we designed and tested a reactive DNS measurement system compatible with OpenINTEL, supported by for further sub-domains. Section II further elaborates on this Apache Kafka message broker functionality. The software can process. query multiple levels in the DNS hierarchy and supports 10 query In addition to storing the IP addresses of name servers types. Initial high-volume testing of the resolver authoritative level shows the software is able to handle large volumes of and domains, name servers also contain other records about queries, but only gives a lower bound on the performance of the domains in their zone. For example, MX records contain the software. Testing of more authoritative levels, testing on purpose- domain names of the servers that handle email traffic for the built hardware and implementation of extended decoder logic and domain, and their priority.

  • DNS for Rocket Scientists Section 1 Overview
    DNS for Rocket Scientists This Open Source Guide is about DNS and (mostly) BIND 9.x on Linux (REDHAT Versions 6.x and 7.x) and the BSD's (FreeBSD, OpenBSD and NetBSD). It is meant for newbies, Rocket Scientist wannabees and anyone in between. This Guide was born out of our first attempts a number of years ago at trying to install a much needed DNS service on an early Redhat Linux system. We completed the DNS 'rite of passage' and found it a pretty unedifying and pointless experience. Health Warning: This is still a work-in-progress. If you have expertise in something - contribute some text. If you find errors don't grumble - tell us. Look at our to do list and if you want to contribute something please do so.

    DNS and BIND David White DNS: Backbone of the Internet • Translates Domains into unique IP Addresses – i.e. “developcents.com” = “66.228.59.103” • Distributed Database of Host Information • Works seamlessly “behind the scenes” So what is a “Domain”? • RFC 920: Domains are Administrative entities • A unique name • Can contain subdomain names Basic Structure • Hierarchical, Tree-like structure • Made up of individual Nodes DNS: Series of Delegated Information A Silly Example… checkers.boardgames.games.fun.com checkers.boardgames.games.fun.com .

ARP was defined by RFC 826 in 1982.[1] It is Internet Standard STD 37. It is also the name of the program for manipulating these addresses in most operating systems. ARP has been implemented in many combinations of network and overlaying internetwork technologies, such as IPv4, Chaosnet, DECnet and Xerox PARC Universal Packet (PUP) using IEEE 802 standards, FDDI, X.25, Frame Relay and Asynchronous Transfer Mode (ATM), IPv4 over IEEE 802.3 and IEEE 802.11 being the most common cases. In Internet Protocol Version 6 (IPv6) networks, the functionality of ARP is provided by the Neighbor Discovery Protocol (NDP). Operating scope The Address Resolution Protocol is a request and reply protocol that runs encapsulated by the line protocol. It is communicated within the boundaries of a single network, never routed across internetwork nodes. This property places ARP into the Link Layer of the Internet Protocol Suite, while in the Open Systems Interconnection (OSI) model, it is often described as residing between Layers 2 and 3, being encapsulated by Layer 2 protocols.
