Yuav ua li cas to taub thaum proxies dag: kev txheeb xyuas ntawm lub cev qhov chaw ntawm lub network proxies siv lub active geolocation algorithm

Cov neeg nyob ib ncig ntawm lub ntiaj teb no siv cov npe lag luam los zais lawv qhov chaw tseeb lossis tus kheej. Qhov no tuaj yeem ua tau los daws ntau yam teeb meem, suav nrog kev nkag mus rau cov ntaub ntawv thaiv lossis ua kom tsis pub leej twg paub.

Tab sis yuav ua li cas yog cov neeg muab kev pab ntawm cov neeg sawv cev zoo li no thaum lawv thov tias lawv cov servers nyob hauv ib lub tebchaws? Qhov no yog cov lus nug tseem ceeb, cov lus teb uas txiav txim siab seb qhov kev pabcuam twg tuaj yeem siv tau los ntawm cov neeg siv khoom uas txhawj xeeb txog kev tiv thaiv cov ntaub ntawv tus kheej.

Ib pawg kws tshawb fawb Asmeskas los ntawm cov tsev kawm qib siab hauv Massachusetts, Carnegie Mellon thiab Stony Brook luam tawm kawm, thaum lub sij hawm qhov chaw tiag tiag ntawm cov servers ntawm xya nrov npe neeg muab kev pabcuam raug kuaj xyuas. Peb tau npaj cov ntsiab lus luv luv ntawm cov txiaj ntsig tseem ceeb.

Taw qhia

Cov neeg ua haujlwm npe npe feem ntau tsis muab cov ntaub ntawv uas tuaj yeem lees paub qhov tseeb ntawm lawv cov lus thov txog qhov chaw server. IP-rau-qhov chaw databases feem ntau txhawb kev tshaj tawm kev tshaj tawm ntawm cov tuam txhab xws li, tab sis muaj pov thawj txaus ntawm qhov tsis raug hauv cov ntaub ntawv no.

Nyob rau hauv txoj kev tshawb no, cov kws tshawb fawb Asmeskas tau soj ntsuam qhov chaw ntawm 2269 lub npe servers ua haujlwm los ntawm xya lub tuam txhab npe thiab nyob hauv tag nrho ntawm 222 lub teb chaws thiab thaj chaw. Qhov kev tshuaj ntsuam tau pom tias tsawg kawg ib feem peb ntawm tag nrho cov servers tsis nyob hauv lub tebchaws uas cov tuam txhab thov hauv lawv cov khoom lag luam. Hloov chaw, lawv nyob hauv cov tebchaws uas pheej yig thiab txhim khu kev qha hosting: Czech koom pheej, Lub teb chaws Yelemees, Netherlands, UK thiab Asmeskas.

Kev txheeb xyuas qhov chaw server

Kev lag luam VPN thiab cov chaw muab kev tso npe tuaj yeem cuam tshuam qhov tseeb ntawm IP-rau-qhov chaw databases - cov tuam txhab muaj peev xwm los tswj, piv txwv li, cov lej chaw nyob hauv cov npe router. Raws li qhov tshwm sim, cov ntaub ntawv kev lag luam tuaj yeem thov ntau qhov chaw muaj rau cov neeg siv, thaum qhov tseeb, kom txuag nyiaj thiab txhim kho kev ntseeg tau, cov servers muaj lub cev nyob hauv ntau lub teb chaws, txawm hais tias IP-rau-qhov chaw databases hais qhov txawv.

Txhawm rau txheeb xyuas qhov chaw tiag tiag ntawm cov servers, cov kws tshawb fawb tau siv lub geolocation algorithm. Nws tau siv los ntsuas qhov kev mus ncig ntawm ib pob ntawv xa mus rau tus neeg rau zaub mov thiab lwm tus tswv tsev paub hauv Is Taws Nem.

Nyob rau tib lub sijhawm, tsuas yog tsawg dua 10% ntawm cov neeg soj ntsuam tau teb rau ping, thiab rau cov laj thawj pom tseeb, cov kws tshawb fawb tsis tuaj yeem khiav ib qho software rau kev ntsuas ntawm lub server nws tus kheej. Lawv tsuas muaj peev xwm xa cov pob ntawv los ntawm tus neeg sawv cev, yog li kev mus ncig mus rau txhua qhov chaw hauv qhov chaw yog qhov sib npaug ntawm lub sijhawm nws yuav siv pob ntawv taug kev los ntawm tus tswv tsev mus rau lub npe thiab los ntawm lub npe mus rau qhov chaw.

Yuav ua li cas to taub thaum proxies dag: kev txheeb xyuas ntawm lub cev qhov chaw ntawm lub network proxies siv lub active geolocation algorithm

Thaum lub sij hawm kev tshawb fawb, software tshwj xeeb tau tsim raws li plaub lub geolocation algorithms: CBG, Octant, Spotter thiab hybrid Octant / Spotter. Kev daws teeb meem code muaj ntawm GitHub.

Txij li nws tsis tuaj yeem cia siab rau IP-rau-qhov chaw khaws ntaub ntawv, rau qhov kev sim cov kws tshawb fawb tau siv RIPE Atlas daim ntawv teev npe thauj tog rau nkoj - cov ntaub ntawv hauv cov ntaub ntawv no muaj nyob hauv online, niaj hnub hloov kho, thiab cov ntaub ntawv qhov chaw muaj tseeb, ntxiv rau. , cov tswv tsev los ntawm cov npe tas li xa cov cim ping rau ib leeg thiab hloov kho cov ntaub ntawv ntawm kev mus ncig hauv cov ntaub ntawv pej xeem.

Tsim los ntawm cov kws tshawb fawb txog kev daws teeb meem, nws yog daim ntawv thov web uas tsim kom muaj kev ruaj ntseg (HTTPS) TCP kev sib txuas hla qhov tsis muaj kev ruaj ntseg HTTP chaw nres nkoj 80. Yog tias tus neeg rau zaub mov tsis mloog ntawm qhov chaw nres nkoj no, ces nws yuav poob tom qab ib qho kev thov, txawm li cas los xij, yog tias tus neeg rau zaub mov mloog. ntawm qhov chaw nres nkoj no, ces tus browser yuav tau txais SYN-ACK teb nrog TLS ClientHello pob ntawv. Qhov no yuav ua rau muaj qhov yuam kev raws tu qauv thiab tus browser yuav tso saib qhov yuam kev, tab sis tsuas yog tom qab qhov thib ob roundtrip.

Txoj kev no, daim ntawv thov lub vev xaib tuaj yeem siv sijhawm ib lossis ob zaug ncig. Ib qho kev pabcuam zoo sib xws tau ua raws li qhov kev pabcuam tau pib los ntawm kab hais kom ua.

Tsis muaj ib qho ntawm cov chaw muab kev kuaj sim qhia qhov tseeb qhov chaw ntawm lawv lub npe servers. Qhov zoo tshaj plaws, cov nroog tau hais, tab sis feem ntau muaj cov ntaub ntawv tsuas yog hais txog lub tebchaws. Txawm hais tias ib lub nroog tau hais, qhov xwm txheej tuaj yeem tshwm sim - piv txwv li, cov kws tshawb fawb tau tshuaj xyuas cov ntaub ntawv teeb tsa ntawm ib lub servers hu ua usa.new-york-city.cfg, uas muaj cov lus qhia rau kev txuas mus rau lub server hu ua chicago.vpn-provider. piv txwv. Yog li, ntau dua lossis tsawg dua qhov tseeb, koj tsuas tuaj yeem paub meej tias tus neeg rau zaub mov belongs rau lub tebchaws tshwj xeeb.

Raws li cov txiaj ntsig ntawm kev sim siv lub geolocation algorithm, cov kws tshawb fawb tau lees paub qhov chaw nyob ntawm 989 tawm ntawm 2269 IP chaw nyob. Nyob rau hauv rooj plaub ntawm 642, qhov no ua tsis tau, thiab 638 yeej tsis nyob hauv lub tebchaws uas lawv yuav tsum nyob, raws li kev lees paub ntawm cov kev pabcuam npe. Ntau tshaj 400 ntawm cov chaw nyob cuav no yeej nyob rau tib lub teb chaws raws li lub teb chaws tshaj tawm.

Qhov chaw nyob yog nyob rau hauv cov teb chaws uas feem ntau siv los tuav servers (nias rau ntawm daim duab kom qhib qhov loj me)

Cov tswv tsev tsis txaus ntseeg tau pom ntawm txhua ntawm xya tus kws kho mob tau sim. Cov kws tshawb fawb nrhiav kev tawm tswv yim los ntawm cov tuam txhab, tab sis txhua tus tsis kam sib tham.
