Ungawedlula Kanjani Ama-Firewall Futhi Uthole Ikheli Langempela Le-IP Lewebhusayithi
Isingeniso
Uma upheqa i-inthanethi, uvamise ukungena kumawebhusayithi usebenzisa amagama azo wesizinda. Kodwa-ke, ngemuva kwezigcawu, amawebhusayithi ahambisa amagama esizinda sawo ngokusebenzisa Amanethiwekhi Okulethwa Kokuqukethwe (ama-CDN) afana ne-Cloudflare ukuze afihle amakheli awo e-IP. Lokhu kubahlinzeka ngezici eziningi, kuhlanganise ne-firewall yohlelo lokusebenza lwewebhu. Kodwa kuthiwani uma udinga ukuthola ikheli le-IP langempela lewebhusayithi? Kulesi sihloko, sizohlola amanye amasu okwenza lokho kanye.
Kungani amawebhusayithi efihla amakheli awo e-IP
Amawebhusayithi afihla amakheli awo e-IP ngezizathu ezahlukahlukene, okuhlanganisa:
- Ukuvikeleka: Ukufihla ikheli le-IP kungenza kube nzima kubahlaseli ukuthi baqalise ukuhlasela kuwebhusayithi.
- Ukusebenza: Ama-CDN angasabalalisa okuqukethwe kwewebhusayithi kumaseva amaningi emhlabeni jikelele, athuthukise izikhathi zokulayisha iwebhusayithi nokuthembeka.
- Ubumfihlo: Abanikazi bewebhusayithi bangase bangafuni ukuveza amakheli abo e-IP kubancintisana nabo noma emphakathini.
Nokho, ngezinye izikhathi ungase odinga ukukwazi ikheli le-IP langempela lewebhusayithi, isibonelo, ukulungisa izinkinga noma ukuhlola ukuphepha.
Izindlela zokuthola ikheli le-IP lewebhusayithi
Kunezindlela ezimbalwa zokuthola ikheli le-IP langempela lewebhusayithi. Ezinye ezivame kakhulu zihlanganisa:
- I-Ping: Ungasebenzisa umyalo we-ping ukuthumela isicelo kuwebhusayithi futhi uthole ikheli layo le-IP. Nokho, lokhu kungase kukunikeze kuphela ikheli le-IP le-CDN hhayi ikheli le-IP langempela lewebhusayithi.
- I-NSLookup: Ungasebenzisa umyalo we-NSLookup ukuze ubheke ikheli le-IP lewebhusayithi Kusistimu Yegama Lesizinda (DNS). Futhi, lokhu kungakunikeza kuphela ikheli le-IP le-CDN.
Ukuthola ikheli le-IP langempela
Ake sibheke isibonelo sendlela yokuthola ikheli le-IP langempela lewebhusayithi. Kulokhu, sizosebenzisa i-streak.com njengesibonelo sethu.
Okokuqala, singazama ukufaka iwebhusayithi futhi senze i-NSLookup. Sithola ikheli le-IP elilandelayo: 104.26.8.186. Kodwa-ke, siyazi ukuthi leli ikheli le-IP le-Cloudflare, njengoba ukuphequlula kulo kusikhombisa ikhasi le-Cloudflare.
Indlela 1: Ukuhlola idatha yomlando ku-SecurityTrails
Enye indlela yokuthola ikheli le-IP langempela lewebhusayithi ukuhlola idatha yayo yomlando kumawebhusayithi afana ne-SecurityTrails. Ngokubheka amarekhodi e-DNS ewebhusayithi, ungase ukwazi ukuthola ikheli le-IP ngaphambi kokuthi iqale ukusebenzisa i-CDN.
Nokho, endabeni ye-streak.com, asikwazanga ukuthola noma iyiphi idatha yomlando esinikeze ikheli le-IP langempela.
Indlela yesi-2: Ukusebenzisa i-Censys ukuthola ikheli le-IP langempela
Enye indlela yokuthola ikheli le-IP langempela lewebhusayithi ukusebenzisa i-Censys. I-Censys iyinjini yokusesha ekhomba amadivayisi namasevisi e-inthanethi, ekuvumela ukuthi useshe Imininingwane mayelana namawebhusayithi.
Ngokuseshela i-streak.com ku-Censys, sikwazile ukuthola amakheli e-IP amaningana ahlotshaniswa newebhusayithi. Ngemva kokuzama ezimbalwa zazo, sithole ikheli le-IP langempela: 130.211.42.74.
Isiphetho
Sengiphetha, kuyilapho ama-CDN afana ne-CloudFlare esiza ukuvikela amawebhusayithi kusuka ukuhlaselwa kwe-cyber, baphinde bafihle ikheli le-IP, okwenza kube inselele ukukhomba ikheli le-IP langempela. Kodwa-ke, sisebenzisa amathuluzi afana ne-SecurityTrails ne-Censys, singazidlula lezi zinqamuleli futhi sithole ikheli le-IP langempela lewebhusayithi, elingasiza ekuphenyeni ukuhlaselwa ku-inthanethi noma ukuhlonza umsuka wethrafikhi esolisayo.
