Privet!
Меня зовут Александр Концевой, и я занимаю должность ведущего специалиста в отделе локальных вычислительных сетей в компании АО «Гринатом».

On this site, I will share my notes, articles, translations, and lab work on networking and other interesting topics. I am convinced that the best way to learn is to teach others, so I decided to share my knowledge with you. Besides, it will help me to organize and save my materials better.

Welcome to my website! I hope you will find a lot of useful information here and will be able to put your knowledge into practice.
