DNS records are used for basic domain redirection thus determining the services you use on the domain. Using individual DNS records, you can identify the hosting for a website, or set up the provider of an email solution.
Individual DNS records can be found through your service provider. If you only use our services you can find the required IP addresses in this useful article How to direct domain to website?
The settings of DNS records themselves must be done with the provider of name servers, where the DNS records are saved. Otherwise, the settings will not influence the workings of the domain itself.

Individual DNS records influence the work of services on a domain. They determine what is shown when the domain is inserted in the address panel of an internet browser, and also define to where e-mails should be delivered.
For example, by creating or deleting A record you "turn on" or "turn off" website showing, otherwise you create a 3rd level domain (sub domain).
Most used DNS records and what they influence:
A record: inserted is IPv4 address. Influences shown websites (website browser prefers IPv4). AAAA: inserted is IPv6 address. Influences shown websites (website browser prefers IPv6). CNAME: inserted is the domain name and only for a subdomain. Redirects subdomain on wanted domain. MX: inserted is the name of the e-mail server (for example mx1.active24.com). This defines to where e-mails are supposed to be sent.
Required DNS records for our services can be found in a creation e-mail which is sent within 30 minutes of service creation. Otherwise you can find them located in this article: How to direct domain to website?
If hosting or e-mail services are not provided by our company, the required DNS records can be found with the provider of the relevant services.
- Log in to Control panel.
- Move to the domain management section (Services/Domains/Domain overview).
- Choose the domain where you want to set up records.
- Click on option: Edit DNS
- Here you can edit, or add, new DNS records.
Detailed walk through
- Using your login information, log in to Control panel. Otherwise you can ask for them here.
- After you are logged in, choose the domain where you wish to set DNS records (Services/Domains/Domain overview).
- Choose DNS administration and check to where the domain is being directed. Domains after registration are directed to our default IP address 220.127.116.11 and don't use any MX records.
- If the domain uses different A or MX records, you can edit them by clicking on the edit button. Alternatively, you can completely delete them by clicking on the trash icon. The Adding of new DNS records is possible by using the Add record button.
Creation of a sub domain is completely free. You just have to create a new DNS record which will direct the sub domain.
For that you can use CNAME record and direct the sub domain to a functional domain. Alternatively, you can create A record and direct the domain towards hosting.
Reverse, called PTR record, is special record in DNS, which offers IP address translation to specific domain. It is reverse process managed by DNS system, which translates better remembered addresses to IP addresses. In that case as visitor of websites you have request from domain -> IP address. If you write to browser https://www.active24.cz and DNS system will figure out, that website is physically located on server with IP address 18.104.22.168.
Your query starts with a domain, which means that you will find this setting through the domain administrator (specifically the DNS server administrator for the domains you set up). But if you wish to request from IP address - > domain, which is managed through reverse record (in case it is set), you have to contact IP address administrator. Which is the one, who offers this IP address, or simplier the internet connection provider (O2, UPC etc.). He can also make any changes to the settings. The reason why reverse records are actually used is primarily the authorization most often within e-mail communications. Some mail servers compare the sender just by the reverse IP address from which the messages are sent.
So, if you are interested in setting this reverse record for your IP address, contact your ISP.
