Komabe, seva ya DNS singayankhe nthawi zina chifukwa chazifukwa zosadziwika, ndiye apa pali zosintha zisanu ndi zitatu zomwe mungayesere ngati seva yanu ya DNS siyikuyankha.

Njira 1: Yambitsaninso Chipangizo chanu

Njira imodzi yosavuta yomwe mungayesere ngati seva ya DNS ya chipangizo chanu sichikuyankha ndikuyambitsanso chipangizo chanu. Ngakhale iyi si njira yotsimikizirika yothetsera vutoli, kuchuluka kwa zovuta zazikulu zomwe mungayambirenso kutha kuthetsedwa sikunganyalanyazidwe.

• Pa Windows, pitani ku Yambani > Chizindikiro cha Mphamvu> Yambitsaninso.

• Pa Android, dinani nthawi yayitali Mphamvu batani kapena dinani batani Mphamvu + Voliyumu Up batani ndikudina Yambitsaninso.

• Pa iPhone, dinani ndikugwira batani M’mbali batani + Volume Up batani ndikukokerani chotsetsereka kumanja kuti muzimitse chipangizocho. Dikirani kwa masekondi 30 ndikudina nthawi yayitali Mbali batani mpaka logo ya Apple ikuwoneka kuti ikuyatsa. Onani odzipereka Yambitsaninso iPhone kalozera kuphunzira momwe kuyambiransoko iPhone wina.

Njira 2: Yesani Msakatuli Wosiyana, DNS, kapena Chipangizo

Kuyesa msakatuli wina kukuthandizani kudziwa ngati pali vuto ndi msakatuli. Mofananamo, kuyesa chipangizo china kudzakuthandizani kudziwa ngati makina a seva ya DNS adasinthidwa ndipo ndi chifukwa chake seva ya DNS ya chipangizo chanu imalephera kuyankha.

Mutha kuyesanso makonda a netiweki yanu popita ku Zokonda > Bwezeretsani Zokonda.

Ngati msakatuli wa DNS sakuyankha, mutha kuyesa kusinthira ku DNS ina monga Cloudflare’s 1.1.1.1, NextDNS, kapena OpenDNS. Njira yosinthira DNS yokhazikika mu Chrome ili mgawo lapamwamba pansi pa Zachinsinsi ndi Chitetezo.

Njira 3: Yatsani posungira DNS

Mutha kutsitsa cache ya DNS mosavuta kuchokera pa Windows terminal. Nayi momwe mungachitire.

Pa Windows

1. Yambitsani Command Prompt.
2. Lembani lamulo lotsatira ndikugunda Lowani kiyi kuti mutsegule cache ya DNS.

ipconfig /flushdns

Izi zichotsa cache ya DNS yotsalira ku Windows ndipo zikuyenera kukuthandizani kuti musakatulenso intaneti momasuka.

Pa Mac

2. Lembani lamulo lotsatira ndikugunda Lowani kiyi.

sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

1. Lowetsani achinsinsi anu a Mac ndikusindikiza batani Lowani kiyi kachiwiri.

Izi zidzakhazikitsanso cache yanu ya DNS nthawi yomweyo.

Njira 4: Yambitsaninso Router Yanu

Router yanu imakhala ndi kiyi pachipata chomwe chimakulolani kuti musakatule intaneti popanda zovuta. Chifukwa chake, ngati DNS ili yosalabadira, ndizotheka kuti pakhoza kukhala cholakwika ndi rauta yamagalimoto kapena pangakhale kusokonekera ngati zida zambiri zilumikizidwa pa netiweki yomweyo. Zikatero, mungafune kuzimitsa rauta yanu ya Wi-Fi ndikuyipatsa mphindi zochepa musanayatse.

Njira 5: Bwezeretsani Zokonda za DNS

Izi zimagwira ntchito pamapulatifomu onse akuluakulu, kuphatikiza Linux. Mukamaliza, yesani kufufuza dzina lachidziwitso, ndipo liyenera kuyamba kugwira ntchito mwachizolowezi.

Njira 6: Lolani Pulogalamu Kudzera pa Firewall

Pali nthawi zina pomwe Antivirus kapena Firewall imatha kuswa DNS. Izi sizichitika kawirikawiri komanso kawirikawiri koma zikhoza kukhala chimodzi mwazifukwa zomwe seva yanu ya DNS imasonyezera kuti siyikuyankha. Ngati mukugwiritsa ntchito pulogalamu ya Antivirus yachitatu, tikupangira kuti muyimitse chitetezo. Yesani kusakatula ndikuwona ngati DNS ikugwiranso ntchito.

Ngati mulibe Antivayirasi wachitatu koma Windows Security, yesani kuletsa chozimitsa moto pa pulogalamu yanu ya msakatuli.

Pa Windows

1. Pitani ku Windows Security > Chitetezo pa intaneti ndi firewall > Lolani pulogalamu kudzera pa firewall.
2. Kenako mutha kuchotsa Google Chrome kuchokera pa chowotchera moto polowera Sinthani makonda > Google Chrome > Chotsani > Chabwino.

Pa Mac

Mutha kulolezanso pulogalamu kudzera pa macOS ‘Firewall pogwiritsa ntchito njira zomwe zili pansipa.

1. Pa Mac yanu, pitani ku Zokonda pa System > Network > Zozimitsa moto > Zosankha. Pamitundu yakale ya macOS, mungafunike kupitako Zokonda pa System > Chitetezo & Zazinsinsi > Zozimitsa moto > Zosankha za Firewall.
2. Tsopano, alemba pa kuphatikiza + chizindikiropezani ndikusankha pulogalamu ya msakatuli kuchokera pa Foda ya Mapulogalamu ndikudina Onjezani.
3. Pulogalamuyi tsopano iwoneka mkati mwa mndandanda wa mapulogalamu ndi ntchito. Kuti muwonetsetse kuti pulogalamuyi ili ndi mwayi wolumikizana ndi maukonde, dinani ndikusankha Lolani malumikizidwe obwera kuchokera pa menyu yotsitsa.
4. Tsopano mukhoza alemba pa Chabwino kusunga zosintha.

Njira 7: Sinthani Kompyuta Yanu

Microsoft imakankhira zosintha zaposachedwa zachitetezo pafupipafupi, ndipo ndizotheka kuti kompyuta yanu mwina siyikhala ndi mtundu waposachedwa wachitetezo. Izi zitha kukhala chifukwa chomwe DNS sichikuyankha pa kompyuta yanu ya Windows kapena Mac.

• Kuti musinthe Windows PC yanu, pitani ku Zokonda > Kusintha kwa Windows > Onani zosintha.

• Kuti musinthe Mac yanu, pitani ku Zokonda pa System > General > Kusintha kwa Mapulogalamu > Sinthani Tsopano.

Njira 8: Yang’anani ndi Wopereka Utumiki Wanu

Nthawi zambiri, zina mwazovuta zomwe mumakumana nazo ndi intaneti yanu ndi chifukwa cha omwe amapereka chithandizo. Mwina ntchito zake zochepa m’malo ena zitha kukhala zotsika, ndipo dera lanu likhoza kukhudzidwa. Kuyimbira foni mwachangu kapena tikiti yothandizira kwa omwe akukuthandizani akuyenera kukuthandizani kudziwa ngati wopereka chithandizo ali ndi vuto ndikuwafunsa kuti athetse vuto lanu la DNS msanga.

Awa ndi mayankho omwe mungayesere ngati seva yanu ya DNS siyikuyankha. Ngati palibe yankho lomwe lakuthandizani, mutha kuyesanso kukhazikitsa Windows osataya deta yanu. Kuchita izi kuyenera kukonzanso kukhazikitsa kwanu kwa Windows ndi zosintha zake kukhala fakitale, ndipo zovuta zanu za DNS zitha kuthetsedwa pambuyo pake.

Kodi mudakumanapo ndi zovuta ndi seva ya DNS? Tiuzeni mu ndemanga pansipa.
