What DNS is, without jargon
Photo: Avila Ops Tecnologia
DNS is your domain’s address list. When someone types suaempresa.com.br, it specifies the computer storing your site and where email goes. The domain is the name; DNS connects it to the right place. A wrong list makes websites vanish and email stop even with everything paid.
DNS often stays with the website builder or a forgotten provider. Supplier changes require list changes. Before contract reviews or supplier switches, know where yours is.
How does it work?
Like a business phone book. “Website” points to hosting’s number. “Email” points to the email service’s number. Each line is a DNS record.
A bakery changes website suppliers but keeps old email service. Only the website line points to the new server. Email remains unchanged and functioning. Accidentally deleting the email line stops incoming messages within hours.
Changes are not immediate. The internet keeps cached lists, so changes take minutes to 48 hours to apply everywhere.
Who should have the DNS password?
You. DNS lives with the domain registrar (Registro.br for .br) or a service you selected. Access must belong to your company’s CNPJ and an email you control. Suppliers may edit but cannot be sole owners.
Supplier-only access makes every change dependent on them. If they disappear, the site is trapped. See DNS: what breaks when someone edits incorrectly and the short definition at avilaops.com/glossario/dns.

Frequently asked questions
Are DNS and domains the same?
No. The domain is your registered name. DNS says where it points. Change hosting or email through DNS without changing the domain.
Must I pay for DNS?
Usually not. Registro.br provides free DNS for .br, as do most hosts.
How long do changes take?
Minutes to 48 hours depending on previous configuration. Schedule website or email moves outside peak business hours.
