About this network

ZONE is operated by Zone Media OU, an Estonian digital marketing and media company.

What it's used for

• The address space carries infrastructure for Zone Media's digital services, with reverse DNS entries like un-75-254.tll01.zonevs.eu and uvn-6-254.hel01.zonevs.eu indicating server or endpoint hosts in Tallinn, Helsinki, and Amsterdam.
• The AS announces 8,704 IPv4 addresses across 6 prefixes and 8 IPv6 prefixes, while maintaining only 4 observed neighbours, a ratio consistent with a hosting or business network rather than a transit provider.
