About AS28725


Ownership and Operational Activity


AS28725, also known as CETIN a.s., is an autonomous system owned by CETIN a.s. The company stands for Česká telekomunikační infrastruktura a.s. and operates in the Czech Republic. It focuses mainly on telecommunication services and infrastructure management, providing services such as internet connectivity, data and voice services, and comprehensive network solutions to other telecommunications operators.



Establishment


While the exact date of establishment for AS28725 is not provided, CETIN a.s. itself was established on June 1, 2015, after splitting from O2 Czech Republic. This division allowed CETIN to focus solely on providing network infrastructure services.



Security Concerns and Malicious Use


As with any large network provider, there are concerns about the potential for misuse of the network by hackers or spammers. According to data retrieved from CleanTalk, a service that monitors and reports on spam and hacking activities, there have been instances where AS28725 has been associated with such malicious activities. However, it's important to note that the presence of malicious activity does not necessarily imply that CETIN a.s. condones or is directly involved in these actions; rather, it may indicate that some of the users within this autonomous system are conducting these activities without the consent or knowledge of the network administrator.
