Domain name

Updated: 30.10.2026Reading time: 1 minute

A domain name is your website’s unique address on the internet, such as nik.ru. It consists of a name and a domain zone, and DNS connects it to the server that runs your website and email.

A domain is registered for a fixed term — usually one year — and should be renewed in advance. It is controlled by its registrant: the person or organisation named at registration.

A short, clear name works for your brand: it is easier to say, print and find. Tip: register the domain in your own or your company’s name rather than your contractor’s, and turn on renewal reminders straight away.

Critical severityTwo vulnerabilities in the PHP core. Fixes are already available.

Protect your website: update PHP

Under certain conditions, an attacker can execute code on the server without a login or password. The website, passwords, keys and any other data the PHP process can access are at risk.

Fixed releases:

Leave the update to specialists

We’ll check your website and server, update PHP, the CMS and extensions with compatibility in mind, and fix any other vulnerabilities we find.

Technical details

Install the fixed release of your branch or your OS vendor’s patched package; there is no need to move to 8.4 specifically. PHP 8.1 and earlier have no official fixes — check for a vendor patch or plan a move to a supported branch.

Updating the CMS alone is not enough: PHP itself must be fixed on the server. Before updating, make a backup and check compatibility; afterwards, restart the PHP services (PHP-FPM, web server) and test your websites.
