Split-Horizon DNS allows the same domain name to return different DNS responses depending on where the request comes from. Internal users can receive private network addresses, while external visitors receive public-facing records. This approach improves security, simplifies network management, and helps organizations keep internal resources inaccessible from the public Internet. It is especially useful for corporate networks, VPN environments, and hybrid infrastructures. Read the full article to discover how Split-Horizon DNS works and when to use it.

SPF record – Definition
The Sender Policy Framework record, or for short, SPF record, is a type of DNS record that specifies which mail servers are authorized to send emails on behalf of a precise domain. The SPF record is a simple text record that defines a list of authorized IP addresses or domain names that are allowed to send emails for that domain. In addition, it prevents email spoofing, which is known for someone sending an email that appears to arrive from a different domain than the one they are actually using.
