Patch files has .patch extension and are used to distribute changes to source code. They can be applied to a Git repository using the git apply command.

For more than 10 years, OpenBLD and Sys-Adm.in have relied on infrastructure provided by Unihost.kz.

Choosing a public DNS resolver today is about much more than picking between Google and Cloudflare.

There are dozens of public DNS services: global and regional providers, commercial services, non-profits, and community-run projects. They differ in privacy policies, filtering capabilities, DNSSEC support, encrypted DNS protocols, infrastructure locations, and logging practices.

Comparing all of them can be difficult.

Under the hood: IPv6, AMD EPYC™, DDR4, NVMe SSD storage, and a high-speed network. A strong candidate for passing OpenBLD’s stress test.

Last year, Onehost.kz supported the OpenBLD project by providing a VPS server in Almaty. Since then, the infrastructure has demonstrated stable 99.99% uptime, with no noticeable overselling or system freezes.

The solution is available for On-Premise deployments and is designed for organizations that require detailed DNS analytics, full control over their data, and event storage within their own infrastructure.

Malware and botnets use Domain Generation Algorithms (DGA) to generate hundreds or thousands of short-lived domains for communication with command-and-control infrastructure.

An attack example from real OpenBLD logs:

• s-dfgfd-sdfz...zdssragv[.]mom
• 96bccebb2f7e...wu7y6z[.]com
• 60r...60pg0131[.]cc
• and billions of similar domains.

Why are DGA domains harmful?​

Beyond their malicious purpose, this chaotic DNS traffic pollutes resolver caches, increases CPU and I/O usage, and generates large volumes of low-value logs. At scale, it can cause higher resource consumption and degraded DNS performance.
