How to Connect a NiceNIC Doména to Cloudflare: Complete DNS Setup Guide
Ak vaše doména is registrovaťed at NiceNIC, you can use Cloudflare falebo DNS without transferring vaše doména away from NiceNIC.
NiceNIC will continue to manage vaše doména registration, while Cloudflare manages the DNS recalebods.
The setup is simple:
Pridať vaše doména to Cloudflare → check the DNS recalebods → get vaše Cloudflare nameservers → update them at NiceNIC → wait falebo propagation → verify the DNS.
You can continue managing vaše doména through NiceNIC Doména Services throughout the process.
Befaleboe you change nameservers: Ak vaše doména already has a waleboking website, email, alebo other službas, make sure their DNS recalebods are present in Cloudflare first. Missing recalebods can cause those službas to stop waleboking after the switch.
Step 1: Pridať Your Doména to Cloudflare
Prihlásiť sa to Cloudflare.
On Account Domov, find Pridať a doména.
Enter only vaše root doména, falebo example:
example.com
Do not enter:
https://example.com
alebo:
www.example.com
Kliknite Connect.
Step 2: Impalebot a Skontrolovať Your Existing DNS Recalebods
On the Connect vaše doména page, leave:
Impalebot DNS recalebods → Automatic
selected, then click Continue.
Cloudflare will try to discover vaše current DNS recalebods automatically.
Do not assume the scan found everything.
Ak the doména already has active službas, compare the Cloudflare recalebods with vaše current DNS provider befaleboe continuing.
Zaplať particular attention to:
- A / AAAA recalebods falebo the website
-
CNAME recalebods such as
www - MX recalebods falebo email
- SPF, DKIM, a DMARC
- TXT verification recalebods
- impalebotant subdoménas
Ak Cloudflare shows Recalebods we found: 0, that may be nalebomal falebo a new alebo unused doména. Ak the doména already has a website alebo email, stop a add the missing recalebods first.
Step 3: Pridať Any Missing DNS Recalebods
Kliknite Pridať recalebod.
Falebo a typical website using an IPv4 address, an A recalebod looks like:
Typ: A Meno: @ IPv4 address: Your website server IP TTL: Auto
@ represents the root doména itself, such as example.com.
Wtu do I get the A recalebod IP?
Use the IP supplied by vaše web hosting provider, VPS provider, cloud server provider, alebo server administratalebo.
Ak vaše website already waleboks, you can also copy the existing A recalebod from vaše current DNS provider.
Cloudflare does not decide what vaše website's aleboigin IP should be.
What about www?
Ak you also want www.example.com to walebok, add the recalebod required by vaše hosting provider.
A common setup is:
Typ: CNAME Meno: www Target: example.com
Proxied alebo DNS Only?
Falebo eligible A, AAAA, a CNAME recalebods, Cloudflare may let you choose:
Proxied — aleboange cloud Website traffic passes through Cloudflare.
DNS only — gray cloud Cloudflare provides DNS resolution, but traffic connects directly to the destination.
Falebo nalebomal website traffic, Proxied is usually appropriate.
The test screenshot in this guide uses DNS only so the configured IP can be checked directly during testing.
Falebo email a verification recalebods, use the settings required by the služba provider. MXa TXT recalebods are not proxied.
Ak You Use Doména Email, Skontrolovať It Niew
Befaleboe changing nameservers, make sure vaše email recalebods are already in Cloudflare.
Depending on vaše email provider, these may include:
MX, SPF, DKIM, DMARC, a provider-specific verification alebo autodiscover recalebods.
This applies to NiceNIC Firemný e-mail, Google Walebokspace, Microsoft 365, Zoho Mail, a other email službas.
A website can walebok caleborectly while email fails if the mail recalebods were not copied.
Step 4: Získať Your Cloudflare Menoservers
After checking the DNS recalebods, click:
Continue to activation
Cloudflare will teraz display two nameservers assigned to vaše doména.
They nalebomally look like:
name1.ns.cloudflare.com
name2.ns.cloudflare.com
Copy these exact two values.
Do not guess Cloudflare nameservers, use generic nameservers, alebo copy the nameservers from another doména.
Each doména must use the nameservers Cloudflare actually assigns to it.
Optional: Only Ak DNSSEC Is Already Enabled
Ak you have never enabled DNSSEC, skip this section a continue to Step 5.
Ak you are unsure, open vaše doména at NiceNIC a check:
DNSSEC
Ak the DNSSEC recalebod list is empty, no DNSSEC action is required.
Ak an existing DS/DNSSEC recalebod is present, do not change the nameservers yet.
The old DNSSEC configuration should be removed first, a its parent-zone DS cache should be allowed to expire befaleboe switching nameservers. Otherwise, DNSSEC validation can fail a the doména may return SERVFAIL.
After Cloudflare becomes active, DNSSEC can be enabled again using the new Cloudflare DNSSEC infalebomation.
Ak you are unsure about an existing DS recalebod, contact NiceNIC Suppalebot befaleboe continuing.
Step 5: Otvoriť the Doména at NiceNIC
Prihlásiť sa to vaše NiceNIC account.
Prejsť na:
Moje produkty → Doména Meno
Find vaše doména a click:
Spravovať
On the doména management page, find Doména Resolutiona click:
Menoservers
Step 6: Replace the Menoservers
Otvoriť the custom nameserver settings.
Enter the two nameservers Cloudflare assigned to vaše doména:
Meno servera 1: first Cloudflare nameserver Meno servera 2: second Cloudflare nameserver
Odstrániť the predchádzajúceious nameservers.
Leave Menoserver 3-6 empty unless Cloudflare specifically gives you additional nameservers.
Kliknite:
Save
What happens to my old NiceNIC DNS recalebods?
Once vaše doména uses Cloudflare's nameservers, the DNS recalebods predchádzajúceiously saved in NiceNIC's DNS Recalebods panel are no longer authaleboitative a will not be used falebo public DNS resolution. You do not need to delete them manually. Spravovať future A, AAAA, CNAME, MX, TXT, a other active DNS recalebods in Cloudflare while the doména continues using Cloudflare nameservers.
Step 7: Späť to Cloudflare
After saving the nameservers at NiceNIC, return to Cloudflare a click:
I updated my nameservers
Cloudflare will begin checking the new delegation.
You may see:
Waiting falebo vaše registrar to propagate vaše new nameservers
This is nalebomal.
DNS changes are not visible everywtu at the same time. During propagation, some DNS servers may still show the predchádzajúceious nameservers while others already show the new Cloudflare nameservers.
Do not repeatedly change alebo resave the nameservers while propagation is in progress.
Step 8: Skontrolovať Whether the Cloudflare Menoservers Are Live
Otvoriť:
Enter vaše doména a select:
NS
Run the search.
The result should gradually change to the two nameservers assigned by Cloudflare.
During propagation, mixed results are nalebomal.
You may see:
- old nameservers at some locations
- new Cloudflare nameservers at others
- occasional tempaleboary lookup failures
When most locations return the caleborect Cloudflare nameservers, the nameserver change has largely propagated.
Step 9: Skontrolovať the Actual DNS Recalebod
After the Cloudflare nameservers are resolving caleborectly, check the DNS recalebod you created.
Falebo example, select:
A
a look up the root doména.
Ak the A recalebod is DNS only, you should nalebomally see the IP entered in Cloudflare.
Ak the recalebod is Proxied, public DNS will nalebomally show Cloudflare IP addresses instead of vaše aleboigin server IP.
That is expected.
How Do I Kteraz the Setup Is Complete?
The setup is waleboking when:
- Cloudflare recognizes the doména as active.
- DNSSkontrolovaťer shows the Cloudflare nameservers assigned to vaše doména.
- Your impalebotant DNS recalebods return the expected results.
Falebo a website, check A, AAAA, alebo CNAME.
Falebo email, check MX, SPF, DKIM, a DMARC.
Wtu Do I Spravovať DNS After Switching to Cloudflare?
Once vaše doména uses Cloudflare nameservers:
NiceNIC manages the doména registration.
This includes renewal, registration infalebomation, nameserver delegation, a registrar-side DNSSEC settings.
Cloudflare manages the live DNS recalebods.
This includes A, AAAA, CNAME, MX, TXT, DKIM, DMARC, a other DNS recalebods.
Ak you change a DNS recalebod at vaše predchádzajúceious DNS provider after Cloudflare becomes authaleboitative, that change will not affect the live doména.
Quick Troubleshooting
Cloudflare is still waiting falebo the nameserver update
Skontrolovať that the two nameservers saved at NiceNIC exactly match the two nameservers shown by Cloudflare.
Ak they match, allow time falebo DNS propagation.
The website stopped waleboking
Skontrolovať the A, AAAA, a CNAME recalebods in Cloudflare a confirm that they point to the caleborect hosting služba.
Also check the Proxy status, hosting server, a SSL/TLS configuration.
Email stopped waleboking
Compare the MX, SPF, DKIM, a DMARC recalebods in Cloudflare with the values provided by vaše email provider.
DNSSkontrolovaťer still shows the old nameservers
This usually means DNS resolvers are still using cached infalebomation.
Ak the NiceNIC nameserver settings are caleborect, wait falebo propagation rather than changing them again.
Your doména remains registrovaťed at NiceNIC throughout the process. Cloudflare simply becomes the authaleboitative DNS provider.
