DNS records are the invisible bridge between your domain name and the server your website runs on. Setting up DNS correctly is key to making your domain point where it should, whether that is your hosting, an email server or other services. This guide shows you how to manage DNS records in the UlozData client zone.
Types of DNS records
Before we get to the settings, here are the most common record types:
- A record: points the domain to a specific IP address (e.g.
93.185.104.10). The basic record for connecting a domain to hosting. - CNAME record: creates an alias that points to another domain (e.g.
www→myweb.com). Used for subdomains. - MX record: tells other servers where to deliver email for your domain. The priority number decides the order of the servers.
- TXT record: a text record used to verify domain ownership, set up SPF for email or configure DKIM.
Tip: If you registered the domain through UlozData and connected it to hosting, the basic DNS records (A, and CNAME for www) are set up automatically. You only need to edit records by hand for advanced configurations.
How to set them up
Sign in and open the domains section
Go to the client zone at ulozdata.cz, sign in with your Wopro account and click “Domény” (Domains) in the left menu. If you do not have an account yet, sign up here.
Select the domain
In the list of domains, click the domain whose DNS you want to edit. The domain detail opens with several tabs.
Go to the DNS records tab
Click the “DNS záznamy” (DNS records) tab. You will see a table of all current records for your domain, showing the type, name, value and TTL (how long the record is kept in cache).
Add or edit a record
To add a new record, click “Přidat záznam” (Add record). Choose the type (A, CNAME, MX, TXT), enter the name (e.g. @ for the main domain or subdomain for a subdomain), fill in the value and confirm. To edit an existing record, click the pencil icon next to it.
Save and wait for the change to spread
Once saved, the change takes effect on our DNS servers immediately. Spreading across the whole internet can take up to 24 hours, depending on the TTL and on how quickly other servers refresh their cache.
Important: Do not delete the default records (especially the NS records and the basic A record) unless you know exactly what you are doing. Deleting the NS records stops your domain from working entirely, and fixing it can take hours.
Tip: A DNS change does not show up everywhere in the world at once. To check whether your record has spread, use an online tool such as dnschecker.org, or wait 24 hours and check again.
Common setup examples
Pointing a domain to hosting
Add an A record with the name @ and the IP address of your hosting as its value. Then add a CNAME record www pointing to yourdomain.com.
Setting up email
Add an MX record with priority 10 and your mail server as its value. For better deliverability, add a TXT record with an SPF rule (e.g. v=spf1 include:mail.ulozdata.cz ~all).
