Microsoft DNS
1 a. Domain Name Service (DNS) encompassing Microsoft DNS From Wikipedia, the free encyclopedia Jump to: navigation, search Microsoft DNS is the name given to the implementation of domain name system services provided in Microsoft Windows operating systems. Contents [hide] 1 Overview 2 DNS lookup client o 2.1 The effects of running the DNS Client service o 2.2 Differences from other systems 3 Dynamic DNS Update client 4 DNS server o 4.1 Common issues 5 See also 6 References 7 External links [edit] Overview The Domain Name System support in Microsoft Windows NT, and thus its derivatives Windows 2000, Windows XP, and Windows Server 2003, comprises two clients and a server. Every Microsoft Windows machine has a DNS lookup client, to perform ordinary DNS lookups. Some machines have a Dynamic DNS client, to perform Dynamic DNS Update transactions, registering the machines' names and IP addresses. Some machines run a DNS server, to publish DNS data, to service DNS lookup requests from DNS lookup clients, and to service DNS update requests from DNS update clients. The server software is only supplied with the server versions of Windows. [edit] DNS lookup client Applications perform DNS lookups with the aid of a DLL. They call library functions in the DLL, which in turn handle all communications with DNS servers (over UDP or TCP) and return the final results of the lookup back to the applications. 2 Microsoft's DNS client also has optional support for local caching, in the form of a DNS Client service (also known as DNSCACHE). Before they attempt to directly communicate with DNS servers, the library routines first attempt to make a local IPC connection to the DNS Client service on the machine. -
Empirical Analysis of the Effects and the Mitigation of Ipv4 Address Exhaustion
TECHNISCHE UNIVERSITÄT BERLIN FAKULTÄT FÜR ELEKTROTECHNIK UND INFORMATIK LEHRSTUHL FÜR INTELLIGENTE NETZE UND MANAGEMENT VERTEILTER SYSTEME Empirical Analysis of the Effects and the Mitigation of IPv4 Address Exhaustion vorgelegt von M.Sc. Philipp Richter geboren in Berlin von der Fakultät IV – Elektrotechnik und Informatik der Technischen Universität Berlin zur Erlangung des akademischen Grades DOKTOR DER NATURWISSENSCHAFTEN -DR. RER. NAT.- genehmigte Dissertation Promotionsausschuss: Vorsitzender: Prof. Dr.-Ing. Sebastian Möller, Technische Universität Berlin Gutachterin: Prof. Anja Feldmann, Ph.D., Technische Universität Berlin Gutachter: Prof. Vern Paxson, Ph.D., University of California, Berkeley Gutachter: Prof. Steve Uhlig, Ph.D., Queen Mary University of London Tag der wissenschaftlichen Aussprache: 2. August 2017 Berlin 2017 Abstract IP addresses are essential resources for communication over the Internet. In IP version 4, an address is represented by 32 bits in the IPv4 header; hence there is a finite pool of roughly 4B addresses available. The Internet now faces a fundamental resource scarcity problem: The exhaustion of the available IPv4 address space. In 2011, the Internet Assigned Numbers Authority (IANA) depleted its pool of available IPv4 addresses. IPv4 scarcity is now reality. In the subsequent years, IPv4 address scarcity has started to put substantial economic pressure on the networks that form the Internet. The pools of available IPv4 addresses are mostly depleted and today network operators have to find new ways to satisfy their ongoing demand for IPv4 addresses. Mitigating IPv4 scarcity is not optional, but mandatory: Networks facing address shortage have to take action in order to be able to accommodate additional subscribers and customers. Thus, if not confronted, IPv4 scarcity has the potential to hinder further growth of the Internet. -

What's New in IPAM 5 out of 8 rated this helpful - Rate this topic Published: June 24, 2013 Updated: July 3, 2014 Applies To: Windows Server 2012, Windows Server 2012 R2 This topic describes the IP Address Management (IPAM) functionality that is new or changed in Windows Server 2012 R2 and Windows Server 2012. IPAM provides highly customizable administrative and monitoring capabilities for the IP address infrastructure on a corporate network. You can monitor, audit, and manage servers running Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS). In this topic: What’s new in IPAM in Windows Server 2012 R2 What’s new in IPAM in Windows Server 2012 What’s new in IPAM in Windows Server 2012 R2 In Windows Server 2012 R2, IPAM offers enhanced support in the following areas.

Stateless DNS
Technical Report KN{2014{DiSy{004 Distributed System Laboratory Stateless DNS Daniel Kaiser, Matthias Fratz, Marcel Waldvogel, Valentin Dietrich, Holger Strittmatter Distributed Systems Laboratory Department of Computer and Information Science University of Konstanz { Germany Konstanzer Online-Publikations-System (KOPS) URL: http://nbn-resolving.de/urn:nbn:de:bsz:352-0-267760 Abstract. Several network applications, like service discovery, file dis- covery in P2P networks, distributed hash tables, and distributed caches, use or would benefit from distributed key value stores. The Domain Name System (DNS) is a key value store which has a huge infrastructure and is accessible from almost everywhere. Nevertheless storing information in this database makes it necessary to be authoritative for a domain or to be \registered" with a domain, e.g. via DynDNS, to be allowed to store and update resource records using nsupdate . Applications like the ones listed above would greatly benefit from a configurationless approach, giving users a much more convenient experience. In this report we describe a technique we call Stateless DNS, which allows to store data in the cache of the local DNS server. It works without any infrastructure updates; it just needs our very simple, configurationless echo DNS server that can parse special queries containing information desired to be stored, process this information, and generate DNS answers in a way that the DNS cache that was asked the special query will store the desired information. Because all this happens in the authority zone of our echo DNS server, we do not cause cache poisoning. Our tests show that Stateless DNS works with a huge number of public DNS servers. -
