What is DNS and how is it configured?

DNS translates a domain name into the address of the server hosting website and email, like a phone book for the internet. When the domain is configured properly, website and email work. In Cantù, near Como, we take care of it for companies in Brianza and Milan.

A, CNAME and MX records are entries in the DNS zone: A links the domain to the server's address, CNAME creates an alias to another name, MX says where to deliver email. A mistake can block website or email: in Como and Brianza we check them from our Cantù office.

DNS propagation is the time it takes for a change to the records to spread across the network, because many servers keep the old copy for a while. It depends on TTL and caching, so it needs planning: for companies between Como, Milan and Lugano we do it without downtime.

Nameservers are the servers that hold the domain's DNS zone and say where website and email are located. Changing them moves the management of all records, so it is best to copy the current zone first. We take care of it from Cantù for companies in Como and Brianza.

To connect a domain to a website, you set a record in the DNS that points to the website's server, then configure the server to recognise that domain and activate the security certificate. From Cantù, in the province of Como, we follow the whole step for companies in Milan and Brianza.

In Cantù you can entrust the DNS configuration to NewVisibility, a web agency with an in-house team in the province of Como, directly managed servers and CSSDA award-winning websites. We look after domains, email and servers together, for companies in Cantù, Como, Brianza and Milan.

The TXT record holds free text and is used to verify domain ownership and to publish email rules such as SPF, DKIM and DMARC. From our Cantù office we manage it for companies in Como, Brianza and Milan, keeping the records tidy and documented.

To verify a domain on Search Console, you usually add a TXT record supplied by the service to the DNS, then check the verification. The same principle applies to other tools. In Cantù, in the province of Como, we do it for companies in Brianza and Milan.

An incorrect DNS configuration in Lugano can be fixed by NewVisibility, an agency based in Cantù (Como) that also supports companies in Canton Ticino. We analyse the DNS zone, correct the records and check that website and email work again, with our own servers and team.

A company's DNS should be managed by a single competent contact, the same one that looks after website, domain and email, with the domain registered in the company's name. This is the model we apply in Cantù, near Como, for businesses in Brianza, Milan and Ticino.

The domain name affects SEO only indirectly: it helps recognition and trust, but content and the technical quality of the website weigh more. From Cantù we help companies in Como and Milan combine domain, website and SEO content.

With a well-prepared move, the website stays online during the domain transfer, because the new environment is copied and tested before the destination is switched. Absolutely no interruption cannot be guaranteed, but good planning reduces it: we handle it from Cantù for companies between Como and Milan.

SPF, DKIM and DMARC are three email authentication systems: SPF lists the servers authorised to send, DKIM signs the message, DMARC decides what to do if the checks fail. They are good practice for businesses in Como, Milan and Lugano.

The server has a significant effect on website response time, together with code, content weight and configuration. That is why in Cantù, in the province of Como, we optimise hosting and website together, also for companies in Brianza, Milan and Lugano with content-rich projects.

The registrar registers the domain and handles its renewals and ownership details, while the maintainer takes care of technical and administrative management, such as DNS and support. Sometimes they are the same. NewVisibility, in Cantù in the province of Como, clarifies the roles for companies in Como, Brianza and Milan.
