CUBIXSERV / Your domain, DNS and service continuity
Domain Names and DNS for Your Website
Connect your domain to your website and email while preserving existing services. Discuss DNS, transfer or registration requirements with us; this page prepares an enquiry rather than reserving a name automatically.
Hosting stores your website’s files and database. The domain is its address; DNS connects that address to services. Domain renewal and hosting renewal are separate.
Choose an extension that suits your audience, such as .fr or .com, and check the registry rules. Confirm eligibility, ownership, renewal price and registrar access. A domain registered elsewhere can stay with its provider; discuss its DNS connection separately.
Domains, email addresses and DNS to connect to your website. Current hosting, available access and migration schedule.
You can keep the domain with its current registrar and connect DNS records to the agreed services. Separate website addresses from mail MX records. Confirm the required values before changing an active zone.
DNS · A / AAAA · CNAME · MX · TXT
A / AAAA
A and AAAA map a name to an IPv4 or IPv6 address.
CNAME
CNAME makes one name an alias of another; it does not redirect a web page.
MX
MX identifies incoming email servers and their priorities.
TXT
TXT publishes verification or policy text; keep records used by active services.
TTL controls how long a record is cached. Lowering it does not clear existing caches.
DNSSEC
DNSSEC authenticates DNS answers. Coordinate keys and the registrar’s DS record before switching providers.

What should I prepare before changing DNS?+
Keep a copy of the current DNS zone, identify the domain owner and check who manages renewal. List the website, email and other services using the domain. A nameserver change affects the whole zone, not only the website, so prepare the replacement records before switching.
Do domain DNS and reverse DNS do the same job?+
No. A and AAAA records direct names to IPv4 and IPv6 addresses; MX records identify email servers. Reverse DNS associates an address with a host name and is managed with the address provider. Check web and email records separately, including the authentication records required by your mail provider.
