About this network

The handle names a group brand that appears nowhere in the company name or the netname.

What it's used for

• A systems integrator's network. One IPv4 /21 announced from Italy, no IPv6, two thousand and forty-eight addresses, through a single observed BGP neighbour.

Notable

• The AS handle is a contraction of the word for information with the word for a group, plus the two letters for an autonomous system. The holder's registered name uses neither word.
• The netname is a country code, the first word of the company name, and the date 20091104.
• The first registrant is not the company but an administrative role for the organisation that holds the registry membership, written as two abbreviations and a title.
• The third contact is the company name again, hyphenated end to end and followed by the word for a role.
• Two thousand addresses, one route, one upstream.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• A registry membership can be held by one entity on behalf of several, which is why the first contact on a block is sometimes an administrator rather than the user. The group brand in the handle and the membership role in the registrant are two views of the same arrangement.
• One route and one upstream on two thousand addresses is a company network that outgrew provider space, not a service network. Nothing here is being sold onward.
