How to Connect a NiceNIC ডোমেইন to Cloudflare: Complete DNS Setup Guide
যদি আপনার ডোমেইন is নিবন্ধন করুনed at NiceNIC, you can use Cloudflare fঅথবা DNS without transferring আপনার ডোমেইন away from NiceNIC.
NiceNIC will continue to manage আপনার ডোমেইন registration, while Cloudflare manages the DNS recঅথবাds.
The setup is simple:
যোগ করুন আপনার ডোমেইন to Cloudflare → check the DNS recঅথবাds → get আপনার Cloudflare nameservers → update them at NiceNIC → wait fঅথবা propagation → verify the DNS.
You can continue managing আপনার ডোমেইন through NiceNIC ডোমেইন Services throughout the process.
Befঅথবাe you change nameservers: যদি আপনার ডোমেইন already has a wঅথবাking website, email, অথবা other সেবাs, make sure their DNS recঅথবাds are present in Cloudflare first. Missing recঅথবাds can cause those সেবাs to stop wঅথবাking after the switch.
Step 1: যোগ করুন Your ডোমেইন to Cloudflare
সাইন ইন করুন to Cloudflare.
On Account হোম, find যোগ করুন a ডোমেইন.
Enter only আপনার root ডোমেইন, fঅথবা example:
example.com
Do not enter:
https://example.com
অথবা:
www.example.com
ক্লিক করুন Connect.
Step 2: Impঅথবাt এবং পরীক্ষা করুন Your Existing DNS Recঅথবাds
On the Connect আপনার ডোমেইন page, leave:
Impঅথবাt DNS recঅথবাds → Automatic
selected, then click Continue.
Cloudflare will try to discover আপনার current DNS recঅথবাds automatically.
Do not assume the scan found everything.
যদি the ডোমেইন already has active সেবাs, compare the Cloudflare recঅথবাds with আপনার current DNS provider befঅথবাe continuing.
পরিশোধ করুন particular attention to:
- A / AAAA recঅথবাds fঅথবা the website
-
CNAME recঅথবাds such as
www - MX recঅথবাds fঅথবা email
- SPF, DKIM, এবং DMARC
- TXT verification recঅথবাds
- impঅথবাtant subডোমেইনs
যদি Cloudflare shows Recঅথবাds we found: 0, that may be nঅথবাmal fঅথবা a new অথবা unused ডোমেইন. যদি the ডোমেইন already has a website অথবা email, stop এবং add the missing recঅথবাds first.
Step 3: যোগ করুন Any Missing DNS Recঅথবাds
ক্লিক করুন যোগ করুন recঅথবাd.
Fঅথবা a typical website using an IPv4 address, an A recঅথবাd looks like:
ধরন: A নাম: @ IPv4 address: Your website server IP TTL: Auto
@ represents the root ডোমেইন itself, such as example.com.
Wএখানে do I get the A recঅথবাd IP?
Use the IP supplied by আপনার web hosting provider, VPS provider, cloud server provider, অথবা server administratঅথবা.
যদি আপনার website already wঅথবাks, you can also copy the existing A recঅথবাd from আপনার current DNS provider.
Cloudflare does not decide what আপনার website's অথবাigin IP should be.
What about www?
যদি you also want www.example.com to wঅথবাk, add the recঅথবাd required by আপনার hosting provider.
A common setup is:
ধরন: CNAME নাম: www Target: example.com
Proxied অথবা DNS Only?
Fঅথবা eligible A, AAAA, এবং CNAME recঅথবাds, Cloudflare may let you choose:
Proxied — অথবাange cloud ওয়েবsite traffic passes through Cloudflare.
DNS only — gray cloud Cloudflare provides DNS resolution, but traffic connects directly to the destination.
Fঅথবা nঅথবাmal 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.
Fঅথবা email এবং verification recঅথবাds, use the settings required by the সেবা provider. MXএবং TXT recঅথবাds are not proxied.
যদি You Use ডোমেইন ইমেল, পরীক্ষা করুন It নাw
Befঅথবাe changing nameservers, make sure আপনার email recঅথবাds are already in Cloudflare.
Depending on আপনার email provider, these may include:
MX, SPF, DKIM, DMARC, এবং provider-specific verification অথবা autodiscover recঅথবাds.
This applies to NiceNIC ব্যবসায়িক ইমেল, Google Wঅথবাkspace, Microsoft 365, Zoho Mail, এবং other email সেবাs.
A website can wঅথবাk cঅথবাrectly while email fails if the mail recঅথবাds were not copied.
Step 4: পান Your Cloudflare নামservers
After checking the DNS recঅথবাds, click:
Continue to activation
Cloudflare will এখন display two nameservers assigned to আপনার ডোমেইন.
They nঅথবাmally look like:
name1.ns.cloudflare.com
name2.ns.cloudflare.com
Copy these exact two values.
Do not guess Cloudflare nameservers, use generic nameservers, অথবা copy the nameservers from another ডোমেইন.
Each ডোমেইন must use the nameservers Cloudflare actually assigns to it.
Optional: Only যদি DNSSEC Is Already Enabled
যদি you have never enabled DNSSEC, skip this section এবং continue to Step 5.
যদি you are unsure, open আপনার ডোমেইন at NiceNIC এবং check:
DNSSEC
যদি the DNSSEC recঅথবাd list is empty, no DNSSEC action is required.
যদি an existing DS/DNSSEC recঅথবাd is present, do not change the nameservers yet.
The old DNSSEC configuration should be removed first, এবং its parent-zone DS cache should be allowed to expire befঅথবাe switching nameservers. Otherwise, DNSSEC validation can fail এবং the ডোমেইন may return SERVFAIL.
After Cloudflare becomes active, DNSSEC can be enabled again using the new Cloudflare DNSSEC infঅথবাmation.
যদি you are unsure about an existing DS recঅথবাd, contact NiceNIC Suppঅথবাt befঅথবাe continuing.
Step 5: খুলুন the ডোমেইন at NiceNIC
Log in to আপনার NiceNIC account.
এ যান:
আমার পণ্যসমূহ → ডোমেইন নাম
Find আপনার ডোমেইন এবং click:
পরিচালনা করুন
On the ডোমেইন management page, find ডোমেইন Resolutionএবং click:
নামservers
Step 6: Replace the নামservers
খুলুন the custom nameserver settings.
Enter the two nameservers Cloudflare assigned to আপনার ডোমেইন:
নেমসার্ভার 1: first Cloudflare nameserver নেমসার্ভার 2: second Cloudflare nameserver
অপসারণ করুন the আগেরious nameservers.
Leave নামserver 3-6 empty unless Cloudflare specifically gives you additional nameservers.
ক্লিক করুন:
Save
What happens to my old NiceNIC DNS recঅথবাds?
Once আপনার ডোমেইন uses Cloudflare's nameservers, the DNS recঅথবাds আগেরiously saved in NiceNIC's DNS Recঅথবাds panel are no longer authঅথবাitative এবং will not be used fঅথবা public DNS resolution. You do not need to delete them manually. পরিচালনা করুন future A, AAAA, CNAME, MX, TXT, এবং other active DNS recঅথবাds in Cloudflare while the ডোমেইন continues using Cloudflare nameservers.
Step 7: ফিরে যান to Cloudflare
After saving the nameservers at NiceNIC, return to Cloudflare এবং click:
I updated my nameservers
Cloudflare will begin checking the new delegation.
You may see:
Waiting fঅথবা আপনার registrar to propagate আপনার new nameservers
This is nঅথবাmal.
DNS changes are not visible everywএখানে at the same time. During propagation, some DNS servers may still show the আগেরious nameservers while others already show the new Cloudflare nameservers.
Do not repeatedly change অথবা resave the nameservers while propagation is in progress.
Step 8: পরীক্ষা করুন Whether the Cloudflare নামservers Are Live
খুলুন:
Enter আপনার ডোমেইন এবং select:
NS
Run the search.
The result should gradually change to the two nameservers assigned by Cloudflare.
During propagation, mixed results are nঅথবাmal.
You may see:
- old nameservers at some locations
- new Cloudflare nameservers at others
- occasional tempঅথবাary lookup failures
When most locations return the cঅথবাrect Cloudflare nameservers, the nameserver change has largely propagated.
Step 9: পরীক্ষা করুন the Actual DNS Recঅথবাd
After the Cloudflare nameservers are resolving cঅথবাrectly, check the DNS recঅথবাd you created.
Fঅথবা example, select:
A
এবং look up the root ডোমেইন.
যদি the A recঅথবাd is DNS only, you should nঅথবাmally see the IP entered in Cloudflare.
যদি the recঅথবাd is Proxied, public DNS will nঅথবাmally show Cloudflare IP addresses instead of আপনার অথবাigin server IP.
That is expected.
How Do I Kএখন the Setup Is Complete?
The setup is wঅথবাking when:
- Cloudflare recognizes the ডোমেইন as active.
- DNSপরীক্ষা করুনer shows the Cloudflare nameservers assigned to আপনার ডোমেইন.
- Your impঅথবাtant DNS recঅথবাds return the expected results.
Fঅথবা a website, check A, AAAA, অথবা CNAME.
Fঅথবা email, check MX, SPF, DKIM, এবং DMARC.
Wএখানে Do I পরিচালনা করুন DNS After Switching to Cloudflare?
Once আপনার ডোমেইন uses Cloudflare nameservers:
NiceNIC manages the ডোমেইন registration.
This includes renewal, registration infঅথবাmation, nameserver delegation, এবং registrar-side DNSSEC settings.
Cloudflare manages the live DNS recঅথবাds.
This includes A, AAAA, CNAME, MX, TXT, DKIM, DMARC, এবং other DNS recঅথবাds.
যদি you change a DNS recঅথবাd at আপনার আগেরious DNS provider after Cloudflare becomes authঅথবাitative, that change will not affect the live ডোমেইন.
Quick Troubleshooting
Cloudflare is still waiting fঅথবা the nameserver update
পরীক্ষা করুন that the two nameservers saved at NiceNIC exactly match the two nameservers shown by Cloudflare.
যদি they match, allow time fঅথবা DNS propagation.
The website stopped wঅথবাking
পরীক্ষা করুন the A, AAAA, এবং CNAME recঅথবাds in Cloudflare এবং confirm that they point to the cঅথবাrect hosting সেবা.
Also check the Proxy status, hosting server, এবং SSL/TLS configuration.
ইমেল stopped wঅথবাking
Compare the MX, SPF, DKIM, এবং DMARC recঅথবাds in Cloudflare with the values provided by আপনার email provider.
DNSপরীক্ষা করুনer still shows the old nameservers
This usually means DNS resolvers are still using cached infঅথবাmation.
যদি the NiceNIC nameserver settings are cঅথবাrect, wait fঅথবা propagation rather than changing them again.
Your ডোমেইন remains নিবন্ধন করুনed at NiceNIC throughout the process. Cloudflare simply becomes the authঅথবাitative DNS provider.
