RFC (Request for Comment) je súbor dokumentov v ktorých sa dokumentujú a zverejňujú štandardy Internetu, návrhy štandardov a obecne odsúhlasené myšlienky.

Tieto dokumenty vám poskytnú najpresnejšie informácie v otázkach napr. elektronickej pošty, formátu správ, protokolov atď. O zverejňovanie a aktualizáciu štandardov sa starajú skupiny World Wide Web Consorcium (vedúci je Tim Berners-Lee, jeden z pôvodných tvorcov webu) a Internet Advisory Board (AIB). Členovia World Wide Web Consorcium (skrátene W3C) reprezentujú súkromné spoločnosti i univerzity spolupracujúce na technickom riešení webových problémov a schvaľovaní štandardov. Internet Advisory Board naproti tomu definuje internetové štandardy. IAB sa skladá zo štyroch hlavných skupín: Internet Engineering Task Force (IETF), Internet Engineering Steering Group (IESG), Internet Research Task Force (IRTF) a Internet Research Steering Group (IRSG). Tieto a ďalšie skupiny vyhodnocujú a testujú návrhy štandardov a predkladajú ich k posúdeniu, či by sa nemohli stať internetovými štandardmi. V súčastnej dobe existuje približne 4000 takýchto štandardov. Na internete možno nájsť niekoľko databáz, ktoré všetky vydané a schválené štandardy obsahujú. Takou je aj databáza nachádzajúca sa na adrese http://www.rfc-editor.org/rfc.html
