DNS Management Software
DNS management software is computer software that controls Domain Name System (DNS) server clusters. DNS data is typically deployed on multiple physical servers. The main purposes of DNS management software are: *to reduce human error when editing complex and repetitive DNS data *to reduce the effort required to edit DNS data *to validate DNS data ''before'' it is published to the DNS servers *to automate the distribution of DNS data Background In 1995, there were only 70,000 domains in existence. The way to register them was by email and the way to publish them was BIND. By mid-1997, the domain count was 1.3 million. As the number of domains aninternet hosts skyrocketed so too did the quantity of DNS data and the time required to manage it. Sysadmins responded by writing Perl or Shell scripts that helped automate DNS changes. These scripts were mostly in-house tools. The closest thing to widely available DNS management software was the BIND module in webmin, which provided web to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Software
Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GeoIP
In computing, Internet geolocation is software capable of deducing the geographic position of a device connected to the Internet. For example, the device's IP address can be used to determine the country, city, or ZIP code, determining its geographical location. Other methods include examination of Wi-Fi hotspots, Data sources An IP address is assigned to each device (e.g. computer, printer) participating in a computer network that uses the Internet Protocol for communication., ''DOD Standard Internet Protocol'' (January 1980) The protocol specifies that each IP packet must have a header which contains, among other things, the IP address of the sender. There are a number of free and paid subscription geolocation databases, ranging from country level to state or city—including ZIP/post code level—each with varying claims of accuracy (generally higher at the country level). These databases typically contain IP address data which may be used in firewalls, ad servers, routing, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ganymede (software)
Ganymede is an open source network directory management framework, designed to allow administrator teams to collaboratively manage subsets of an organization's directory services, such as NIS, DNS, Active Directory / LDAP, DHCP, and RADIUS, among others. First announced and released at the 1998 USENIX LISA conference, Ganymede has been under public development and use since then. Ganymede uses a central server which supports clients connecting via Java RMI. The Ganymede server maintains a transactional object graph database of network information such as user objects, group objects, system objects, network objects, etc. Users and administrators run Ganymede clients (GUI or XML based) to create, modify, or delete objects in the database. Whenever a user commits a transaction, the Ganymede server schedules a number of background threads to write out updated network source files and run whatever system scripts are required to propagate the new data into the managed network direc ...

IP Address Management
IP address management (IPAM) is a methodology implemented in computer software for planning and managing the assignment and use of IP addresses and closely related resources of a computer network. It does not typically provide Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP) services, but manages information for these components. Additional functionality, such as controlling reservations in DHCP and other data aggregation and reporting capabilities, is also common. Data tracked by an IPAM system may include information such as IP addresses in use, and the associated devices and users. Centralized collection of this information may support troubleshooting and abuse investigations. IPAM tools are increasingly important as new IPv6 Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic acros ...

Comparison Of DNS Server Software
This article presents a comparison of the features, platform support, and packaging of many independent implementations of Domain Name System (DNS) name server software. Servers compared Each of these DNS servers is an independent implementation of the DNS protocols, capable of resolving DNS names for other computers, publishing the DNS names of computers, or both. Excluded from consideration are single-feature DNS tools (such as proxies, filters, and firewalls) and redistributions of servers listed here (many products repackage BIND, for instance, with proprietary user interfaces). DNS servers are grouped into several categories of specialization of servicing domain name system queries. The two principal roles, which may be implemented either uniquely or combined in a given product are: * Authoritative server: authoritative name servers publish DNS mappings for domains under their ''authoritative'' control. Typically, a company (e.g. "Acme Example Widgets") would provide its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knot DNS
Knot DNS is an open-source authoritative-only server for the Domain Name System. It was created from scratch and is actively developed by CZ.NIC, the .CZ domain registry. The purpose of this project is to supply an alternative open-source implementation of an authoritative DNS server suitable for TLD operators to increase overall security, stability and resiliency of the Domain Name System. It is implemented as a multi-threaded daemon, using a number of programming techniques and data structures to make the server very fast, notably Read-copy-update or a special kind of a radix tree. Knot DNS uses a zone parser written in Ragel to achieve very fast loading of the zones at the startup. It is also able to add and remove zones on the fly by changing the configuration file and reloading the server using the 'knotc' utility. Since version 3.0.0, Knot DNS supports a high performance XDP mode in Linux, which can improve response performance significantly. Changelog New in 1.2.0 ...

Microsoft DNS
Microsoft DNS is the name given to the implementation of domain name system services provided in Microsoft Windows operating systems. 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. 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 ...

Critical Internet Infrastructure
__NOTOC__ Critical Internet infrastructure is a collective term for all hardware and software systems that constitute essential components in the operation of the Internet. Background Several studies and events have helped to define the scope of critical Internet infrastructure. In August 2013, Internet infrastructure experts including Yuval Shavitt, Bill Woodcock, Rossella Mattioli, Thomas Haeberlen, Ethan Katz-Bassett and Roland Dobbins convened for six days at Schloss Dagstuhl to refine the academic and policy understanding of critical Internet infrastructure, producing a number of papers in the process. In 2017, the Global Commission on the Stability of Cyberspace undertook a global survey of Internet infrastructure experts in order to assess the degree of consensus on what constituted critical Internet infrastructure, producing a '' Definition of the Public Core'' which has since been used by the OECD and others as a standardized description of the principal elements of Inter ...
