Pasina DNS maseva, hatingakwanise kusevha internet sezvatinoita mazuva ese, tekinoroji iyi yanga yakakosha kweanopfuura makore makumi matatu, asi iko zvino yave kuvandudzwa. Hongu, isu tiri kutaura nezvekuuya kweiyo EDNS yekuwedzera iyo "inovandudza" pfungwa yeDNS.
Kana isu tichinyora kero yewebhusaiti mubhurawuza yeURL bar, inongotumira chikumbiro kuInternet operator's DNS (Domain Name System) sevha yekugadzirisa iyo IP kero, iyo inopihwa kune iro zita rezita.
EDNS uye kuti inovandudza sei DNS kuti ikurumidze uye yakachengeteka zvakanyanya
Kana kero yeIP (Internet Protocol) yawanikwa, chimwe chikumbiro chinotumirwa kuIP (Internet Protocol) kungowana data rinodiwa kuendesa peji rewebhu.
Zvisinei, kuti udzidze zvakawanda nezve EDNS, tichakuudza kuti EDNS chii uye kuti ichavandudza sei DNS, ichiita kuti ikurumidze uye yakachengeteka. Silent Revolution ichavandudza kubhurawuza kwedu kwezuva nezuva painternet pasina isu kana kucherechedza.
Iyo Internet Injiniya Task Force (IETF) yagara ichibvumidza kusvika kweiyo RFC 6891 yakatarwa, kana Extension Mechanisms yeDNS (EDNS). Chiyero ichi chakatanga kushanda muna Kukadzi 1, 2019. Uye kwete izvozvo chete, asi zvakare yakaunza nhevedzano yekuvandudza kune iripo DNS kana DNS.
Chii chinonzi EDNS, uye inovandudza sei DNS kukurumidza uye yakachengeteka?
Iyo DNS system ine basa rekushandura kero kana maURL atinopinda mubrowser pakero yeIP inoenderana kuti titange kubatana. Kusvikira 1983, iyo HOST system yakashandiswa, faira inochengeta zvese zvinozivikanwa zveInternet domains, asi izvi zvakave zvisingagoneke nekuda kwekuputika kweInternet.
Nhasi, maDNS ekuwedzera masisitimu ave nesimba, chisikwa chichaita kuti DNS maseva akurumidze uye ashande zvakanyanya kupfuura kare. Kwete chete izvi zvinogona kuita shanduko nyore nyore kana kuvandudza kukurumidza kwavanodudzirwa, asi matanho ekuchengetedza anogona kuisirwa kudzivirira kurwiswa kweDDoS.
Haisi yekutanga kudhindwa yeDNS Extension System (EDNS), seyokutanga yakabudiswa muna 1999 neInternet Engineering Task Force seRFC 2671. Zvisinei, izvi zvakatoziviswa kuti hazvichashandi neRFC 6891 tsanangudzo. Sezvineiwo, sevashandisi, haufanirwe kunetseka nezve chero chinhu nekuti zvese shanduko nekuvandudzwa zvinoenderana nemakambani ane chekuita neDNS.
Nekudaro, isu ticharamba tichifamba zvakajairwa uye kutora mukana wekuvandudza, izvo dzimwe nguva zvakavanzika. Mukubatana nemakambani, ivo vanozofanira kutarisa kana system yavo inoenderana nayo, uye kana zvisiri, vanozofanirwa kugadzirisa kune mitsva mitsva.
Zvakare, hofori hombe dzeinternet dzakadai seGoogle, Cisco, CleanBrowsing, Cloudflare, Facebook, Internet Systems Consortium, PowerDNS uye Quad9 dzakatogadziriswa. Zvakanaka, unofungei pamusoro peizvi? Goverana maonero ako ese uye pfungwa muchikamu chemashoko pazasi. Uye kana waifarira chinyorwa ichi, usakanganwa kugovera chinyorwa ichi neshamwari dzako nemhuri.
