How to Connect a NiceNIC Domain to Cloudflare: Complete DNS Setup Guide
Ha a te domain is regisztrációed at NiceNIC, you can use Cloudflare fvagy DNS without transferring a te domain away from NiceNIC.
NiceNIC will continue to manage a te domain registration, while Cloudflare manages the DNS recvagyds.
The setup is simple:
Hozzáadás a te domain to Cloudflare → check the DNS recvagyds → get a te Cloudflare nameservers → update them at NiceNIC → wait fvagy propagation → verify the DNS.
You can continue managing a te domain through NiceNIC Domain Services throughout the process.
Befvagye you change nameservers: Ha a te domain already has a wvagyking website, email, vagy other szolgáltatáss, make sure their DNS recvagyds are present in Cloudflare first. Missing recvagyds can cause those szolgáltatáss to stop wvagyking after the switch.
Step 1: Hozzáadás Your Domain to Cloudflare
Bejelentkezés to Cloudflare.
On Account Kezdőlap, find Hozzáadás a domain.
Enter only a te root domain, fvagy example:
example.com
Do not enter:
https://example.com
vagy:
www.example.com
Kattintson Connect.
Step 2: Impvagyt és Ellenőrzés Your Existing DNS Recvagyds
On the Connect a te domain page, leave:
Impvagyt DNS recvagyds → Automatic
selected, then click Continue.
Cloudflare will try to discover a te current DNS recvagyds automatically.
Do not assume the scan found everything.
Ha the domain already has active szolgáltatáss, compare the Cloudflare recvagyds with a te current DNS provider befvagye continuing.
Fizetés particular attention to:
- A / AAAA recvagyds fvagy the website
-
CNAME recvagyds such as
www - MX recvagyds fvagy email
- SPF, DKIM, és DMARC
- TXT verification recvagyds
- impvagytant subdomains
Ha Cloudflare shows Recvagyds we found: 0, that may be nvagymal fvagy a new vagy unused domain. Ha the domain already has a website vagy email, stop és add the missing recvagyds first.
Step 3: Hozzáadás Any Missing DNS Recvagyds
Kattintson Hozzáadás recvagyd.
Fvagy a typical website using an IPv4 address, an A recvagyd looks like:
Típus: A Név: @ IPv4 address: Your website server IP TTL: Auto
@ represents the root domain itself, such as example.com.
Witt do I get the A recvagyd IP?
Use the IP supplied by a te web hosting provider, VPS provider, cloud server provider, vagy server administratvagy.
Ha a te website already wvagyks, you can also copy the existing A recvagyd from a te current DNS provider.
Cloudflare does not decide what a te website's vagyigin IP should be.
What about www?
Ha you also want www.example.com to wvagyk, add the recvagyd required by a te hosting provider.
A common setup is:
Típus: CNAME Név: www Target: example.com
Proxied vagy DNS Only?
Fvagy eligible A, AAAA, és CNAME recvagyds, Cloudflare may let you choose:
Proxied — vagyange cloud Website traffic passes through Cloudflare.
DNS only — gray cloud Cloudflare provides DNS resolution, but traffic connects directly to the destination.
Fvagy nvagymal 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.
Fvagy email és verification recvagyds, use the settings required by the szolgáltatás provider. MXés TXT recvagyds are not proxied.
Ha You Use Domain Email, Ellenőrzés It Nemw
Befvagye changing nameservers, make sure a te email recvagyds are already in Cloudflare.
Depending on a te email provider, these may include:
MX, SPF, DKIM, DMARC, és provider-specific verification vagy autodiscover recvagyds.
This applies to NiceNIC Üzleti e-mail, Google Wvagykspace, Microsoft 365, Zoho Mail, és other email szolgáltatáss.
A website can wvagyk cvagyrectly while email fails if the mail recvagyds were not copied.
Step 4: Szerezzen Your Cloudflare Névservers
After checking the DNS recvagyds, click:
Continue to activation
Cloudflare will most display two nameservers assigned to a te domain.
They nvagymally look like:
name1.ns.cloudflare.com
name2.ns.cloudflare.com
Copy these exact two values.
Do not guess Cloudflare nameservers, use generic nameservers, vagy copy the nameservers from another domain.
Each domain must use the nameservers Cloudflare actually assigns to it.
Optional: Only Ha DNSSEC Is Already Enabled
Ha you have never enabled DNSSEC, skip this section és continue to Step 5.
Ha you are unsure, open a te domain at NiceNIC és check:
DNSSEC
Ha the DNSSEC recvagyd list is empty, no DNSSEC action is required.
Ha an existing DS/DNSSEC recvagyd is present, do not change the nameservers yet.
The old DNSSEC configuration should be removed first, és its parent-zone DS cache should be allowed to expire befvagye switching nameservers. Otherwise, DNSSEC validation can fail és the domain may return SERVFAIL.
After Cloudflare becomes active, DNSSEC can be enabled again using the new Cloudflare DNSSEC infvagymation.
Ha you are unsure about an existing DS recvagyd, contact NiceNIC Suppvagyt befvagye continuing.
Step 5: Megnyitás the Domain at NiceNIC
Bejelentkezés to a te NiceNIC account.
Ugrás ide:
Termékeim → Domain Név
Find a te domain és click:
Kezelés
On the domain management page, find Domain Resolutionés click:
Névservers
Step 6: Replace the Névservers
Megnyitás the custom nameserver settings.
Enter the two nameservers Cloudflare assigned to a te domain:
Névszerver 1: first Cloudflare nameserver Névszerver 2: second Cloudflare nameserver
Eltávolítás the előzőious nameservers.
Leave Névserver 3-6 empty unless Cloudflare specifically gives you additional nameservers.
Kattintson:
Save
What happens to my old NiceNIC DNS recvagyds?
Once a te domain uses Cloudflare's nameservers, the DNS recvagyds előzőiously saved in NiceNIC's DNS Recvagyds panel are no longer authvagyitative és will not be used fvagy public DNS resolution. You do not need to delete them manually. Kezelés future A, AAAA, CNAME, MX, TXT, és other active DNS recvagyds in Cloudflare while the domain continues using Cloudflare nameservers.
Step 7: Vissza to Cloudflare
After saving the nameservers at NiceNIC, return to Cloudflare és click:
I updated my nameservers
Cloudflare will begin checking the new delegation.
You may see:
Waiting fvagy a te registrar to propagate a te new nameservers
This is nvagymal.
DNS changes are not visible everywitt at the same time. During propagation, some DNS servers may still show the előzőious nameservers while others already show the new Cloudflare nameservers.
Do not repeatedly change vagy resave the nameservers while propagation is in progress.
Step 8: Ellenőrzés Whether the Cloudflare Névservers Are Live
Megnyitás:
Enter a te domain és select:
NS
Run the search.
The result should gradually change to the two nameservers assigned by Cloudflare.
During propagation, mixed results are nvagymal.
You may see:
- old nameservers at some locations
- new Cloudflare nameservers at others
- occasional tempvagyary lookup failures
When most locations return the cvagyrect Cloudflare nameservers, the nameserver change has largely propagated.
Step 9: Ellenőrzés the Actual DNS Recvagyd
After the Cloudflare nameservers are resolving cvagyrectly, check the DNS recvagyd you created.
Fvagy example, select:
A
és look up the root domain.
Ha the A recvagyd is DNS only, you should nvagymally see the IP entered in Cloudflare.
Ha the recvagyd is Proxied, public DNS will nvagymally show Cloudflare IP addresses instead of a te vagyigin server IP.
That is expected.
How Do I Kmost the Setup Is Complete?
The setup is wvagyking when:
- Cloudflare recognizes the domain as active.
- DNSEllenőrzéser shows the Cloudflare nameservers assigned to a te domain.
- Your impvagytant DNS recvagyds return the expected results.
Fvagy a website, check A, AAAA, vagy CNAME.
Fvagy email, check MX, SPF, DKIM, és DMARC.
Witt Do I Kezelés DNS After Switching to Cloudflare?
Once a te domain uses Cloudflare nameservers:
NiceNIC manages the domain registration.
This includes renewal, registration infvagymation, nameserver delegation, és registrar-side DNSSEC settings.
Cloudflare manages the live DNS recvagyds.
This includes A, AAAA, CNAME, MX, TXT, DKIM, DMARC, és other DNS recvagyds.
Ha you change a DNS recvagyd at a te előzőious DNS provider after Cloudflare becomes authvagyitative, that change will not affect the live domain.
Quick Troubleshooting
Cloudflare is still waiting fvagy the nameserver update
Ellenőrzés that the two nameservers saved at NiceNIC exactly match the two nameservers shown by Cloudflare.
Ha they match, allow time fvagy DNS propagation.
The website stopped wvagyking
Ellenőrzés the A, AAAA, és CNAME recvagyds in Cloudflare és confirm that they point to the cvagyrect hosting szolgáltatás.
Also check the Proxy status, hosting server, és SSL/TLS configuration.
Email stopped wvagyking
Compare the MX, SPF, DKIM, és DMARC recvagyds in Cloudflare with the values provided by a te email provider.
DNSEllenőrzéser still shows the old nameservers
This usually means DNS resolvers are still using cached infvagymation.
Ha the NiceNIC nameserver settings are cvagyrect, wait fvagy propagation rather than changing them again.
Your domain remains regisztrációed at NiceNIC throughout the process. Cloudflare simply becomes the authvagyitative DNS provider.
