About this network

NETOPS is operated by NETOPS B.V., a European managed cloud infrastructure provider based in Amsterdam.

What it's used for

• The address space carries managed cloud and email filtering infrastructure, as indicated by the reverse DNS entries out160-64.emailfilter.io and out160-127.emailfilter.io.
• The AS announces 1024 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining 51 observed routing neighbours. This ratio of limited address space to a high number of peering partners indicates a transit or interconnection role rather than a large-scale access network.
• Traffic from this AS consists of business cloud services, managed infrastructure, and email filtering endpoints provided to corporate clients across Europe.

Notable

• Registrants for all announced prefixes align with the AS holder, listing NETOPS IP Admin and NETOPS NOC as the responsible parties.
• The inventory consists of three distinct IPv4 blocks, including a /23 and two /24s, alongside a single /48 IPv6 prefix, reflecting a compact corporate estate.
