In computing, naming schemes are often used for objects connected into computer networks. ==Naming schemes in computing== Server naming is a common tradition. It makes it more convient to refer to a machine by name than by its IP address. CIA named their servers after states.〔http://www.itworld.com/offbeat/61750/would-server-any-other-name-be-functional〕 Server names may be named by their role or follow a common theme such as colors, countries, cities, planets, chemical element, scientists, etc. If servers are in multiple different geographical locations they may be named by closest airport code. Such as web-01, web-02, web-03, mail-01, db-01, db-02. Airport code example: lax-001 lax-002 arn-001 City-State-Nation example: 3-character unique numeric number 2-character production/development classifier 3-character city ID 2-character state/province/region ID 2-character nation ID Thus, a production server in Minneapolis, Minnesota would be nnn.ps.min.mn.us.example.com, or a development server in Vancouver, BC, would be nnn.ds.van.bc.ca.example.com. Large networks often use a systematic naming scheme, such as using a location (e.g. a department) plus a purpose to generate a name for a computer. For example, a web server in NY may be called "nyc-www-04.xyz.net". Common network naming convention: ''(city-function-number.domain.name)'' City Code IATA link * nyc-pdc-201.xyz.net * lon-rtr-901.xyz.net * hkg-san-541.xyz.net * mos-gpc-400.xyz.net If you have many offices in a city distinguish the offices designate * 100–199 ABC location * 200–299 CDE location ... * 700–799 Extranet * 800–899 DMZ * 900–999 Internet * gpc - General PC * prn - Printer * www - Web server * dbs - Database server * fps - File and print server * app - Application server * fin - Finance server * swi - Network switch * ifw - Internal firewall * efw - External firewall * rtr - Router * wap - Wireless access point (RFC 1178 link ) However, smaller networks will frequently use a more personalized naming scheme to keep track of the many hosts. Popular naming schemes include trees, planets, rocks, etc. (antiquated). Network naming can be hierarchical in nature, such as the Internet's Domain Name System. Indeed, the Internet employs several universally applicable naming methods: uniform resource name (URN), uniform resource locator (URL), and uniform resource identifier (URI).
