AS20746 — ASN-IDC T.NO.OM.I.NC

AS20746 announces 159 IPv4 prefixes covering 215,552 addresses and 1 IPv6 prefixes.

About this network

The AS handle ASN-IDC T.NO.OM.I.NC is held by Telecom Italia S.p.A., the leading Italian telecommunications provider.

What it's used for

• The address space carries business and enterprise services, evidenced by netnames such as IT-INTERBUSINESS-20020708 and IT-FULLCOMPANY-20001017, and reverse DNS entries like host-81-126-200-0.business.telecomitalia.it.
• With 215,296 IPv4 addresses announced across 229 prefixes and only 12 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

• Registrants for the largest prefixes consistently identify Telecom Italia S.p.A. or its business units, such as Interbusiness Network Administration Staff and IT Telecom Role, aligning with the announcer.
• The address inventory is finely subdivided into numerous /21 and /20 blocks, reflecting a large internal corporate estate segmented by service type or site rather than a single monolithic allocation.
