Hosting, domains and DNS explained simply
Three things business owners pay for every year without quite knowing what they are. Here is the plain version — it takes five minutes.
Domain, hosting and DNS
The domain is the address people type; you rent it, usually annually. Hosting is where the files and database physically live — a server running around the clock.
DNS is the directory translating the address into the server's numeric address. Changing hosting means changing DNS records; propagation takes minutes to a day.
The records that matter
An A record points the domain at a server IP, CNAME aliases one name to another, and MX decides where email for your domain goes.
The practical consequence: moving a site does not touch MX unless you replace the whole record set with the new host's defaults — which is exactly how email breaks during migrations.
Email on your own domain
An address like info@yourdomain.uz costs very little and noticeably affects trust compared with a free mailbox.
To stay out of spam folders you need SPF, DKIM and DMARC records. Without them your domain is an unverified sender and order notifications may quietly fail to arrive.
