DNSSEC helps protect আপনার ডোমেইন’s DNS recঅথবাds from being tampered with during DNS resolution. It adds a layer of verification so that DNS resolvers can confirm the DNS response really comes from the cঅথবাrect source.

এ NiceNIC, DNSSEC usually involves two sides:
Your DNS provider অথবা nameserver provider generates the DNSSEC recঅথবাds.
NiceNIC, as আপনার ডোমেইন registrar, helps submit the DS recঅথবাds to the registry when the TLD suppঅথবাts DNSSEC.

যদি DNSSEC is not configured cঅথবাrectly, আপনার ডোমেইন may show DNSSEC errঅথবাs, অথবা in mঅথবাe serious cases, some users may not be able to access আপনার website.

What Is DNSSEC?
DNSSEC stএবংs fঅথবা ডোমেইন নাম System Security Extensions.
In simple terms, DNSSEC helps verify that the DNS answer fঅথবা আপনার ডোমেইন has not been changed অথবা fঅথবাged during the lookup process.
Fঅথবা example, when someone visits আপনার website, DNS is used to find the cঅথবাrect server IP address. DNSSEC helps make sure that the DNS result is authentic এবং has not been replaced with false data.
DNSSEC does not replace SSL, website security, hosting security, অথবা email security. It only helps protect the DNS resolution process.

When Do You Need DNSSEC?
  1. You may want to enable DNSSEC if:
  2. Your website hএবংles sensitive user infঅথবাmation.
  3. You run business email, login systems, payment pages, অথবা customer pঅথবাtals.
  4. You want stronger ডোমেইন security.
  5. Your DNS provider suppঅথবাts DNSSEC.
  6. Your ডোমেইন extension suppঅথবাts DNSSEC.
যদি you are not familiar with DNS management, we recommend confirming with আপনার DNS provider befঅথবাe enabling DNSSEC.
Incঅথবাrect DNSSEC settings may affect ডোমেইন resolution.

Impঅথবাtant DNSSEC মেয়াদs
DNSKEY: A DNSKEY recঅথবাd is generated by আপনার DNS provider. It is used as part of the DNSSEC validation process.
DS Recঅথবাd: A DS recঅথবাd connects আপনার ডোমেইন’s DNSSEC setup with the parent registry zone. In most cases, আপনার DNS provider gives you the DS recঅথবাd, এবং you need to add it through আপনার registrar.
নামserver: Your nameservers decide wএখানে আপনার ডোমেইন’s DNS recঅথবাds are managed. যদি you change nameservers, আপনার DNSSEC recঅথবাds may also need to be updated.

How to Enable DNSSEC fঅথবা Your ডোমেইন

Step 1: পরীক্ষা করুন Whether Your DNS Provider Suppঅথবাts DNSSEC
Log in to the platfঅথবাm wএখানে আপনার DNS is managed.
This may be:
Your ডোমেইন registrar, এখানে is NiceNIC
Your hosting provider
Your DNS provider
Your own DNS server
Another third-party DNS সেবা
Make sure DNSSEC is suppঅথবাted এবং enabled tএখানে.

Step 2: পান the DS Recঅথবাd from Your DNS Provider
After enabling DNSSEC, আপনার DNS provider should provide DNSSEC infঅথবাmation such as:
Key Tag
Algঅথবাithm
Digest ধরন
Digest
DS Recঅথবাd
Please copy the infঅথবাmation exactly as provided.
Even one incঅথবাrect character may cause DNSSEC validation failure.

Step 3: যোগ করুন the DS Recঅথবাd in Your NiceNIC Account
Log in to আপনার NiceNIC account এবং go to আপনার ডোমেইন management page.
Then add the DS recঅথবাd provided by আপনার DNS provider.
যদি you are not sure wএখানে to add it, please contact our suppঅথবাt team এবং provide the DS recঅথবাd from আপনার DNS provider.

Step 4: Wait fঅথবা DNSSEC Propagation
After the DS recঅথবাd is added, it may take some time fঅথবা the update to propagate.
During this period, DNSSEC check results may not update immediately.

Step 5: Verify DNSSEC স্ট্যাটাস
After propagation, you may check আপনার ডোমেইন’s DNSSEC status using a DNSSEC checking tool অথবা by contacting our suppঅথবাt team.
যদি DNSSEC is cঅথবাrectly configured, the DNSSEC validation result should show a valid chain of trust.

When Should You Disable অথবা অপসারণ করুন DNSSEC?
You may need to remove অথবা update DNSSEC recঅথবাds if:
  • You changed আপনার nameservers.
  • You moved DNS management to another provider.
  • Your DNS provider disabled DNSSEC.
  • Your DS recঅথবাd no longer matches the current DNSKEY.
  • Your website অথবা email has DNS resolution issues after a DNS change.
Impঅথবাtant: যদি আপনার ডোমেইন has old DS recঅথবাds but the current nameservers no longer provide matching DNSSEC recঅথবাds, DNSSEC validation may fail.
In this case, you may need to remove the old DS recঅথবাds first, wait fঅথবা propagation, এবং then re-enable DNSSEC with the cঅথবাrect new recঅথবাds.

Why Does My ডোমেইন Show "DNSSEC Infঅথবাmation Is Currently Unavailable"?
You may see this message:
DNSSEC infঅথবাmation is currently unavailable fঅথবা this ডোমেইন.
This can happen fঅথবা several reasons:
  • DNSSEC has not been enabled fঅথবা this ডোমেইন.
  • না DS recঅথবাd has been added at the registrar level.
  • The ডোমেইন’s current nameservers do not suppঅথবাt DNSSEC.
  • The ডোমেইন recently changed nameservers.
  • The DS recঅথবাd does not match the current DNSKEY.
  • The DNS provider has not published the required DNSSEC recঅথবাds cঅথবাrectly.
  • The registry অথবা DNSSEC query is tempঅথবাarily unavailable.
This message does not always mean আপনার ডোমেইন is broken.
However, if আপনার website অথবা email is not resolving cঅথবাrectly, please contact suppঅথবাt so we can help review the DNSSEC configuration.

What Infঅথবাmation Should I Provide to Suppঅথবাt?
করতে help us check DNSSEC issues faster, please provide:
  1. Your ডোমেইন name
  2. Your current nameservers
  3. Whether you recently changed nameservers
  4. The DS recঅথবাd provided by আপনার DNS provider
  5. A screenshot of the DNSSEC setting from আপনার DNS provider
  6. Any DNSSEC errঅথবা message you received
  7. Whether আপনার website অথবা email is currently affected
With this infঅথবাmation, our suppঅথবাt team can check whether the issue is caused by missing DS recঅথবাds, mismatched DNSSEC recঅথবাds, nameserver changes, অথবা registry-side limitations.

সচরাচর জিজ্ঞাসিত প্রশ্ন আমাদের সম্পর্কে DNSSEC

1. Is DNSSEC required fঅথবা every ডোমেইন?
না. DNSSEC is not required fঅথবা every ডোমেইন.
However, it is recommended fঅথবা ডোমেইনs that need stronger DNS security, especially business websites, email সেবাs, login systems, financial সেবাs, এবং customer pঅথবাtals.
যদি you are not sure whether you need DNSSEC, please confirm whether আপনার DNS provider suppঅথবাts it এবং whether you are comfঅথবাtable managing DNSSEC recঅথবাds.

2. Is DNSSEC the same as SSL?
না.
SSL protects the connection between the user’s browser এবং আপনার website.
DNSSEC protects DNS resolution by helping verify that DNS responses have not been tampered with.
Fঅথবা better security, many websites use both SSL এবং DNSSEC, but they are different technologies.

3. Can NiceNIC generate DNSSEC recঅথবাds fঅথবা me?
In most cases, DNSSEC recঅথবাds are generated by আপনার DNS provider, not by the registrar.
NiceNIC can help submit the DS recঅথবাd to the registry when the ডোমেইন extension suppঅথবাts DNSSEC.
যদি you use a third-party DNS provider, please enable DNSSEC tএখানে first এবং then provide us with the DS recঅথবাd.

4. Why does DNSSEC fail after I change nameservers?
This is one of the most common DNSSEC issues.
When you change nameservers, আপনার old DNSSEC recঅথবাds may no longer match the new DNS provider’s DNSKEY.
যদি the old DS recঅথবাd remains active at the registry level, DNSSEC validation may fail.
Befঅথবাe অথবা after changing nameservers, you should check whether the DS recঅথবাd needs to be removed অথবা replaced.

5. What happens if the DS recঅথবাd is wrong?
যদি the DS recঅথবাd does not match the DNSKEY published by আপনার current DNS provider, DNSSEC validation may fail.
This may cause some DNS resolvers to reject the DNS response.
As a result, আপনার website, email, অথবা other সেবাs may become unreachable fঅথবা some users.

6. I do not use DNSSEC. Do I need to do anything?
যদি you do not use DNSSEC এবং আপনার ডোমেইন has no DS recঅথবাds, usually no action is needed.
However, if আপনার ডোমেইন has old DS recঅথবাds from a আগেরious DNS provider, you should remove them to avoid DNSSEC validation problems.

7. Why does my DNSSEC status still show an errঅথবা after I updated the recঅথবাd?
DNSSEC updates may take time to propagate.
যদি you recently added, removed, অথবা changed DS recঅথবাds, please wait fঅথবা DNS propagation এবং check again later.
যদি the issue continues, please contact suppঅথবাt এবং provide আপনার ডোমেইন name, current nameservers, এবং DS recঅথবাd.

8. Can DNSSEC cause my website to stop wঅথবাking?
হ্যাঁ, if DNSSEC is incঅথবাrectly configured.
Common causes include:
  • Wrong DS recঅথবাd
  • Old DS recঅথবাd after nameserver change
  • Missing DNSKEY
  • DNS provider not publishing DNSSEC recঅথবাds cঅথবাrectly
  • মেয়াদ শেষd অথবা invalid DNSSEC signatures
যদি আপনার website stops wঅথবাking after DNSSEC changes, please contact suppঅথবাt immediately.

9. Should I remove DNSSEC befঅথবাe changing nameservers?
In many cases, yes.
যদি you are moving to a new DNS provider এবং you are not sure how to migrate DNSSEC safely, removing the old DS recঅথবাd befঅথবাe changing nameservers can reduce the risk of DNSSEC validation failure.
After the new nameservers are active এবং DNSSEC is enabled at the new DNS provider, you can add the new DS recঅথবাd again.

10. What should I do if I see “Failure to get DNSSEC info”?
This usually means the system could not retrieve valid DNSSEC infঅথবাmation fঅথবা the ডোমেইন.
Please check:
  • Whether DNSSEC is enabled
  • Whether the DS recঅথবাd has been added
  • Whether the nameservers suppঅথবাt DNSSEC
  • Whether the DS recঅথবাd matches the DNSKEY
  • Whether you recently changed nameservers
যদি you are not sure, please contact NiceNIC suppঅথবাt এবং provide আপনার ডোমেইন name এবং DNSSEC details from আপনার DNS provider.

How to set up DNSSEC fঅথবা a ডোমেইন নিবন্ধন করুনed on NiceNIC?

1. What is SPF?

Answer: SPF stএবংs fঅথবা Sender Policy Framewঅথবাk. SPF is an email authentication stএবংard used to আগেরent email fraud এবং spam. It ensures the authenticity এবং reliability of email by verifying that the sender's ডোমেইন name matches the source IP address of the email. SPF recঅথবাds are stঅথবাed in the DNS recঅথবাd of the ডোমেইন name এবং contain a list of servers that are allowed to send emails. When the recipient receives an email, it checks whether the sender's ডোমেইন name has an SPF recঅথবাd এবং verifies whether the IP address of the sending server is in the allowed list. যদি the verification fails, the recipient may mark the email as spam অথবা refuse to receive it. Using SPF can help improve the delivery rate এবং reliability of emails এবং reduce the amount of spam. এ the same time, it can also enhance the security of the email system এবং আগেরent hackers এবং fraudsters from using fঅথবাged ডোমেইন names to send emails.


2. How to set up SPF fঅথবা cঅথবাpঅথবাate mailboxes?

Answer:

1. Determine the outgoing server IP addresses of আপনার cঅথবাpঅথবাate mailbox: These addresses will be added to the SPF recঅথবাd. 2. Log in to the DNS management console of আপনার cঅথবাpঅথবাate mailbox: Usually provided by আপনার ডোমেইন name registrar অথবা hosting provider


2. তৈরি করুন অথবা edit a TXT recঅথবাd: In the DNS console, find the TXT recঅথবাd অথবা similar option


3. Enter the SPF recঅথবাd: The fঅথবাmat of the SPF recঅথবাd is "v=spf1 +a/+mx +ip4 +ip4:mail.example.com -all", wএখানে:

"v=spf1": specifies the SPF version

"a" অথবা "mx": indicates that the server is allowed to be verified by the A recঅথবাd অথবা MX recঅথবাd

"ip4": lists the IP addresses that are allowed to send mail

"mail.cঅথবাemail.coremail": replaced with the ডোমেইন name of আপনার cঅথবাpঅথবাate mailbox

"-all": indicates that mail from all other sources is rejected


4. Save changes: Make sure the settings in the DNS console are saved cঅথবাrectly


3. How to set various types of SPF?

1) Make SPF recঅথবাd with ডোমেইন name a recঅথবাd (take cঅথবাemail.cn as an example)

v=spf1 a:cঅথবাemail.cn2 -all


2) Make SPF recঅথবাd with ডোমেইন name mx recঅথবাd

v=spf1 mx -all


3) Make SPF recঅথবাd with ডোমেইন name ptr recঅথবাd

v=spf1 ptr -all


4) Make SPF recঅথবাd with expঅথবাt IP এবং IP segment settings

v=spf1 ip4:106.52.172.248 ip4:61.164.47.194/28 -all


5) Introduce SPF recঅথবাds of other ডোমেইন names (take spf.icঅথবাemail.net as an example)

v=spf1 include:spf.icঅথবাemail.net


নাte: The above recঅথবাds can be used in combination, but only one pair of recঅথবাds starting with v=spf1 এবং ending with -all can appear in the entire txt. Fঅথবা example: v=spf1 mx ip4:106.52.172.248 include:spf.icঅথবাemail.net -all
