Whois check

WHOIS ay isang network utility na ginagamit para sa pagtatanong ang mga database na tindahan ang mga inarkila ng mga kliyente o mga appointees ng isang asset sa Internet, halimbawa, ang isang pangalan ng lugar, ang isang IP lokasyon piraso, o isang malayang framework, pa ay bukod pa rito na ginagamit para sa isang mas malawak na saklaw ng iba pang mga data. Ang convention sa mga tindahan at mga nagbibigay ng nilalaman ng database sa isang maaaring maunawaan ang mga pag-aayos. WHOIS administrations ay karaniwang inihatid ng paggamit ng mga Transmission Control Protocol (TCP).

Server makinig sa mga pangangailangan sa numero ng port 43. Mga customer ay mga pangunahing mga application na gumawa ng isang correspondences channel sa server, magpadala ng isang talaan ng nilalaman gamit ang pangalan ng mga asset na maaaring questioned at inaasahan ang reaksyon sa paghahayag ng isang pagpapangkat ng nilalaman talaan na matatagpuan sa database. Ito effortlessness ng convention bukod pa rito ay nagbibigay-daan sa isang application, at ang isang bayad na linya interface client, sa pagtatanong ng isang WHOIS server ng paggamit ng Telnet convention.WHOIS lookup ay sa pangkalahatan ay gumanap na may isang pagkakasunod-sunod line interface ng application, ngunit ngayon maraming mga pagpipilian ng mga electronic na mga instrumento umiiral.

Isang WHOIS database ay binubuo ng isang hanay ng mga nilalaman ng mga talaan para sa bawat asset. Ang mga nilalaman ng mga talaan ay binubuo ng iba ' t-ibang mga bagay ng data tungkol sa mga asset mismo, at anumang kaugnay na data ng mga pinili, registrants, pangangasiwa ng data, halimbawa, paglikha at pagwawakas ng. Two information models exist for putting away asset data in a WHOIS database, the thick and the flimsy model.

WHOIS data can be saved turned toward to either a thick or a flimsy information model: A Thick WHOIS server stores the complete WHOIS data from all the recorders for the specific set of information (so that one WHOIS server can react with WHOIS data on all .org spaces, halimbawa). A Thin WHOIS server stores just the name of the WHOIS server of the recorder of a space, which thus has the full subtle elements on the information being found, (halimbawa, the .com WHOIS servers, which allude the WHOIS question to the enlistment center where the area was enlisted). The thick model typically guarantees predictable information and somewhat speedier questions, since one and only WHOIS server needs to be reached.

In the event that an enlistment center goes bankrupt, a thick registry contains extremely essential data (if the registrant entered right information, and security gimmicks were not used to cloud the information) and enrollment data can be held. Be that as it may with a dainty registry, the contact data may not be accessible, and it could be troublesome for the legitimate registrant to hold control of the area. On the off chance that a WHOIS customer did not see how to manage this circumstance, it would show the full data from the enlistment center.

Tragically, the WHOIS convention has no standard for deciding how to recognize the slim model from the thick model. Particular subtle elements of which records are put away change among space name registries. Some top-level areas, including com and net, work a flimsy WHOIS, obliging area recorders to keep up their own particular clients’ impormasyon. The other worldwide top-level registries, including org, work a thick model.[4] Each nation code top-level registry has its own particular national principles.

WHOIS customers generally perform the WHOIS questions specifically and afterward arrange the results for showcase. A lot of people such customers are restrictive, created by area name enlistment centers. The requirement for electronic customers originated from the way that summon line WHOIS customers generally existed just in the Unix and substantial figuring planets.

Microsoft Windows and Macintosh machines had no WHOIS customers introduced of course, so recorders needed to figure out how to give access to WHOIS information to potential clients. Numerous end-clients still depend on such customers, despite the fact that order line and graphical customers exist now for most home PC stages. Microsoft gives the Sysinternals Suite that incorporates a whois customer at no expense.
