About this network

TESKE-VIRTUAL-SYSTEM is operated by Teske Virtual System LTDA.

What it's used for

• The address space carries business hosting and virtual server infrastructure, evidenced by the netname TESKE-CGNT-NET-1 and reverse DNS entries like 38-172-195-64.isp.teske.com.br and www.fatelecom.tec.br.
• The AS announces 512 IPv4 addresses across 2 prefixes and 2 IPv6 prefixes, while maintaining 29 observed neighbours; this ratio of limited address space against a moderate number of peers indicates a hosting or service provider role rather than a large-scale access network.
• Traffic from this AS consists of web hosting, VPS instances, and BGP-enabled services for business clients, consistent with the operator's stated focus on virtual server solutions and colocation.

Notable

• Registrants are mixed: 38.172.195.0/24 is registered to TESKE VIRTUAL SYSTEM LTDA with netname TESKE-CGNT-NET-1, while 44.30.174.0/24 is registered to Amateur Radio Digital Communications with netname AMPRNET.
• The address inventory is small and subdivided, with one prefix clearly associated with the operator's ISP services and another associated with amateur radio digital communications.
