Why is my domain name resolving not active?

The following reasons may cause your domain resolving not to take effect.

1. The domain name's DNS is not configured to the correct DNS as requested. Please make sure that the DNS are ns1.dns-diy.net and ns2.dns-diy.net, or the IP addresses of the DNS are the same as ns1.dns-diy.net or/and ns2.dns-diy.net.

2. Please make sure input the right data in "data" and "host" column.


Why is the DNS still showing the old one when I check it even if I have modified it with the registrar?

Our DNS check is based on the current data of the DNS root server. If you modify DNS with the registrar, it will take about 12-72 hours to be reflected on the root server.


What is domain resolving?

Domain resolving is actually the converting process of tying text-based domain names to the numeric IP Addresses that are necessary to locate the domain name's server on the net. For the convenience of memory, IP addresses are replaced by domain names to identify the websites. The resolving of domains is done by DNS servers.


What is A record?

A (Address) record is the corresponding IP address used to specify hostname (or domain name). You can point the website servers under your appropriate domain to your own web servers and setup sub-domains for your domains at the same time.


What is CNAME Record?

CNAME is canonical name record. Such record allows you to map more than one name to the same computer and it is generally applying to the computers offering web and email services on the same one. For example, there is a computer named 'host.mydomain.com' (A record) offering both www and mail services. For the users' convenience to access the websites, you can give two CNAME to the computer: www and mail. The full names of these two aliases are www.mydomain.com and mail.mydomain.com, actually both of them are pointing to host.mydomain.com.


How to check whether the name servers have been setup as valid ones?

You can check whether the DNS has been configured correctly on the right site of DNS-DIY reseller control panel. To change your domains' DNS, please go to your control panel of your current registrar.


I am a reseller, how to make my customers do domain resolving by themselves?

As a reseller, you can just change the domain name's DNS to the correct DNS, telling your customer the domain administration password, then your customer can log in directly to http://www.dns-diy.com, enter the domain and domain administration password to resolve online.


What are SPF Record and TXT Record

Sender Policy Framework (SPF), is an email validation system designed to prevent email spam by tackling source address spoofing, a common vulnerability. SPF allows administrators to specify which hosts are allowed to send email from a given domain by creating SPF record in the DNS.

Example SPF record: "v=spf1 mx -all" (Allow domain's MXes to send mail for the domain, prohibit all others)

s ** generation of the string command depends on the mail service provider.

TXT (text) Record is used to hold some text information. You can put virtually any free text you want within a TXT record. TXT record is used to define Sender Policy Framework (SPF) and DomainKeys Signed Mail (DKIM) information records which may be used to validate legitimate email sources from a domain, to prevent emails being faked to appear to have been sent from you.


Can I setup wildcard DNS records to my domain names?

Yes. Please input '*'  in hostname.


What is MX record?

MX record is the mail exchange record. You may point your mail server under your appropriate domain names to your own mail server, and manage all the mail settings by yourself. Just fill in the IP address of your server online, it will help you forward all the emails under your appropriate domain name to your own mail server.


What is the TTL?

The full name of TTL is "Time To live". In short, it refers to the keeping time of DNS record at DNS server. Below is an example to explain what is TTL's value.

Supposing there is a domain myhost.abc.com (Actually this is a DNS record, it generally means that there is a host computer called myhost in the domain abc.com). its corresponding IP address is 1.1.1.1, and its TTL is 10 minutes. This domain or this record is kept in a DNS server called dns.abc.com.

Now if an user inputs the following address (or URL): http://myhost.abc.com, what will happen next?

The DNS server 8.8.8.8 appointed by the user (or the DNS assigned automatically by his ISP, network provider) will try to explain him myhost.abc.com, surely the DNS server 8.8.8.8 can't resolve right away since it doesn't include the records of myhost.abc.com. But through the recursive search of DNS in the world, it finally goes to the server dns.abc.com.

The DNS server dns.abc.com informs the DNS server 8.8.8.8 the corresponding IP address of myhost.abc.com, and then 8.8.8.8 informs the user of the result. To speed up the resolving of this record, 8.8.8.8 will keep the result 1.1.1.1 for a period of time, that is called TTL time. In this period, if the user requests to resolve myhost.abc.com again, 8.8.8.8 will tell the user directly. While if the TTL time is outdated, the whole process will be repeated.


What kinds of domain name can be supported by DNS-DIY?

Any domain names including multilingual domain names, can be resolved by DNS-DIY online. Such as, .com, .net, .org, .biz, .info, .name, .cn, .us, .cc, .tv, etc.

Please note in order for the ns records taking effect, you need to change the DNS of domain name to ns1/ns2.dns-diy.net.


Why has not MX records taken into effect?

Most of SMTP requires MX record to be pointed to a hostname instead of IP address.

For example, if you would like to setup 218.5.1.249 as the mail server of whatis.cn, you can configure in this way,

1. Resolve mail.whatis.cn to 218.5.1.249 (please fill in mail for host column, and choose A for type column, then fill in 218.5.1.249 for data column, click 'Add' button).

2. Please configure the MX record of whatis.cn as mail (leave host column, choose MX for type column, fill in mail for data column and then click 'Add' button.)

3. Configurate your email server at 218.5.1.249 to accept emails for @whatis.cn.

If you fill in mail for host column in the second step, then all the emails sent to @mail.whatis.cn (not @whatis.cn) will be received by 218.5.1.249. This may not meet with your original intention.


Why is priority always setting as '0'?

The priority value is only effective on MX record. For other types of records, the value will be abandoned.


Why can't I receive emails when the resolving has taken effect?

1. Please check whether your MX record is setup correctly;

2. Please check to see if your mail server is setup correctly.

You may try our mail forwarding service if you don't own an email server.
