How to Connect a NiceNIC Domän to Cloudflare: Complete DNS Setup Guide

Om din domän is registreraed at NiceNIC, you can use Cloudflare feller DNS without transferring din domän away from NiceNIC.

NiceNIC will continue to manage din domän registration, while Cloudflare manages the DNS recellerds.

The setup is simple:

Lägg till din domän to Cloudflare → check the DNS recellerds → get din Cloudflare nameservers → update them at NiceNIC → wait feller propagation → verify the DNS.

You can continue managing din domän through NiceNIC Domän Services throughout the process.
Befellere you change nameservers: Om din domän already has a wellerking website, email, eller other tjänsts, make sure their DNS recellerds are present in Cloudflare first. Missing recellerds can cause those tjänsts to stop wellerking after the switch.

Step 1: Lägg till Your Domän to Cloudflare

Logga in to Cloudflare.

On Account Start, find Lägg till a domän.

Enter only din root domän, feller example:

example.com

Do not enter:

https://example.com

eller:

www.example.com

Klicka Connect.

Step 2: Impellert och Kontrollera Your Existing DNS Recellerds

On the Connect din domän page, leave:

Impellert DNS recellerds → Automatic

selected, then click Continue.

Cloudflare will try to discover din current DNS recellerds automatically.

Do not assume the scan found everything.

Om the domän already has active tjänsts, compare the Cloudflare recellerds with din current DNS provider befellere continuing.

Betala particular attention to:

• A / AAAA recellerds feller the website
• CNAME recellerds such as www
• MX recellerds feller email
• SPF, DKIM, och DMARC
• TXT verification recellerds
• impellertant subdomäns

Om Cloudflare shows Recellerds we found: 0, that may be nellermal feller a new eller unused domän. Om the domän already has a website eller email, stop och add the missing recellerds first.

Step 3: Lägg till Any Missing DNS Recellerds

Klicka Lägg till recellerd.

Feller a typical website using an IPv4 address, an A recellerd looks like:

Typ:  A  Namn: @  IPv4 address: Your website server IP  TTL: Auto

@ represents the root domän itself, such as example.com.

Whär do I get the A recellerd IP?

Use the IP supplied by din web hosting provider, VPS provider, cloud server provider, eller server administrateller.

Om din website already wellerks, you can also copy the existing A recellerd from din current DNS provider.

Cloudflare does not decide what din website's ellerigin IP should be.

What about www?

Om you also want www.example.com to wellerk, add the recellerd required by din hosting provider.

A common setup is:

Typ: CNAME  Namn: www  Target: example.com

Proxied eller DNS Only?

Feller eligible A, AAAA, och CNAME recellerds, Cloudflare may let you choose:

Proxied — ellerange cloud Webbsite traffic passes through Cloudflare.

DNS only — gray cloud Cloudflare provides DNS resolution, but traffic connects directly to the destination.

Feller nellermal 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.

Feller email och verification recellerds, use the settings required by the tjänst provider. MXoch TXT recellerds are not proxied.

Om You Use Domän E-post, Kontrollera It Nejw

Befellere changing nameservers, make sure din email recellerds are already in Cloudflare.

Depending on din email provider, these may include:

MX, SPF, DKIM, DMARC, och provider-specific verification eller autodiscover recellerds.

This applies to NiceNIC Företagsmail, Google Wellerkspace, Microsoft 365, Zoho Mail, och other email tjänsts.

A website can wellerk cellerrectly while email fails if the mail recellerds were not copied.

Step 4: Få Your Cloudflare Namnservers

After checking the DNS recellerds, click:

Continue to activation

Cloudflare will nu display two nameservers assigned to din domän.

They nellermally look like:

name1.ns.cloudflare.com

name2.ns.cloudflare.com

Copy these exact two values.

Do not guess Cloudflare nameservers, use generic nameservers, eller copy the nameservers from another domän.

Each domän must use the nameservers Cloudflare actually assigns to it.

Optional: Only Om DNSSEC Is Already Enabled

Om you have never enabled DNSSEC, skip this section och continue to Step 5.

Om you are unsure, open din domän at NiceNIC och check:

DNSSEC

Om the DNSSEC recellerd list is empty, no DNSSEC action is required.

Om an existing DS/DNSSEC recellerd is present, do not change the nameservers yet.

The old DNSSEC configuration should be removed first, och its parent-zone DS cache should be allowed to expire befellere switching nameservers. Otherwise, DNSSEC validation can fail och the domän may return SERVFAIL.

After Cloudflare becomes active, DNSSEC can be enabled again using the new Cloudflare DNSSEC infellermation.

Om you are unsure about an existing DS recellerd, contact NiceNIC Suppellert befellere continuing.

Step 5: Öppna the Domän at NiceNIC

Logga in to din NiceNIC account.

Gå till:

Mina produkter → Domän Namn

Find din domän och click:

Hantera

On the domän management page, find Domän Resolutionoch  click:

Namnservers

Step 6: Replace the Namnservers

Öppna the custom nameserver settings.

Enter the two nameservers Cloudflare assigned to din domän:

Nameserver 1: first Cloudflare nameserver Nameserver 2: second Cloudflare nameserver

Ta bort the föregåendeious nameservers.

Leave Namnserver 3-6 empty unless Cloudflare specifically gives you additional nameservers.

Klicka:

Save

Step 7: Tillbaka to Cloudflare

After saving the nameservers at NiceNIC, return to Cloudflare och click:

I updated my nameservers

Cloudflare will begin checking the new delegation.

You may see:

Waiting feller din registrar to propagate din new nameservers

This is nellermal.

DNS changes are not visible everywhär at the same time. During propagation, some DNS servers may still show the föregåendeious nameservers while others already show the new Cloudflare nameservers.

Do not repeatedly change eller resave the nameservers while propagation is in progress.

Step 8: Kontrollera Whether the Cloudflare Namnservers Are Live

Öppna:

DNSKontrolleraer.org

Enter din domän och select:

NS

Run the search.

The result should gradually change to the two nameservers assigned by Cloudflare.

During propagation, mixed results are nellermal.

You may see:

• old nameservers at some locations
• new Cloudflare nameservers at others
• occasional tempellerary lookup failures

When most locations return the cellerrect Cloudflare nameservers, the nameserver change has largely propagated.

Step 9: Kontrollera the Actual DNS Recellerd

After the Cloudflare nameservers are resolving cellerrectly, check the DNS recellerd you created.

Feller example, select:

A

och look up the root domän.

Om the A recellerd is DNS only, you should nellermally see the IP entered in Cloudflare.

Om the recellerd is Proxied, public DNS will nellermally show Cloudflare IP addresses instead of din ellerigin server IP.

That is expected.

How Do I Knu the Setup Is Complete?

The setup is wellerking when:

1. Cloudflare recognizes the domän as active.
2. DNSKontrolleraer shows the Cloudflare nameservers assigned to din domän.
3. Your impellertant DNS recellerds return the expected results.

Feller a website, check A, AAAA, eller CNAME.

Feller email, check MX, SPF, DKIM, och DMARC.

Whär Do I Hantera DNS After Switching to Cloudflare?

Once din domän uses Cloudflare nameservers:

NiceNIC manages the domän registration.

This includes renewal, registration infellermation, nameserver delegation, och registrar-side DNSSEC settings.

Cloudflare manages the live DNS recellerds.

This includes A, AAAA, CNAME, MX, TXT, DKIM, DMARC, och other DNS recellerds.

Om you change a DNS recellerd at din föregåendeious DNS provider after Cloudflare becomes authelleritative, that change will not affect the live domän.

Quick Troubleshooting

Cloudflare is still waiting feller the nameserver update

Kontrollera that the two nameservers saved at NiceNIC exactly match the two nameservers shown by Cloudflare.

Om they match, allow time feller DNS propagation.

The website stopped wellerking

Kontrollera the A, AAAA, och CNAME recellerds in Cloudflare och confirm that they point to the cellerrect hosting tjänst.

Also check the Proxy status, hosting server, och SSL/TLS configuration.

E-post stopped wellerking

Compare the MX, SPF, DKIM, och DMARC recellerds in Cloudflare with the values provided by din email provider.

DNSKontrolleraer still shows the old nameservers

This usually means DNS resolvers are still using cached infellermation.

Om the NiceNIC nameserver settings are cellerrect, wait feller propagation rather than changing them again.

Your domän remains registreraed at NiceNIC throughout the process. Cloudflare simply becomes the authelleritative DNS provider.
