About this network

The AS handle GRTN-AS is held by Terna S.p.A., the Italian electricity transmission system operator.

What it's used for

• The address space carries infrastructure for Terna's grid operations, evidenced by the netname GRTN-NET and registrant Terna S.p.A.
• The inventory consists of a single IPv4 prefix, 193.108.204.0/24, comprising 256 addresses, with 1 observed neighbour, indicating a small, isolated internal network rather than a transit or access provider.

Notable

• The registrant Terna S.p.A. aligns directly with the AS holder, confirming the space is owned and operated by the utility itself.
• The address inventory is minimal, consisting of only one /24 block, which is typical for a corporate entity managing specific internal systems rather than a large-scale internet service provider.
