AS14745 — INTERNAP-BLOCK-4

AS14745 announces 54 IPv4 prefixes covering 41,472 addresses and 1 IPv6 prefixes.

About this network

Two different AS numbers carry the same handle, and one reverse lookup answers with a bare domain name and no host part at all.

What it's used for

• A hosting and connectivity network. 43,008 addresses across 56 IPv4 prefixes plus one IPv6 prefix, 2600:c0b::/32, with 13 observed BGP neighbours.

Notable

• The AS handle is INTERNAP-BLOCK-4, which is also the handle recorded for a different AS in this same range.
• Nearly every prefix carries the netname UG-210, and one carries PNAP-06-2001.
• The registrant alternates between PF IPV4 Borrower, LLC and Unitas Global from block to block.
• One of eighteen sampled addresses returned a name, and that name is zipdata.net.

Interesting

• A reverse lookup that answers with a bare domain is unusual. Normally a host label sits in front of it, so the name identifies a machine; here the zone was configured with the domain apex itself, and the answer names an organisation rather than anything on the network.
• One netname across almost the whole estate says the space was acquired as a unit rather than accumulated. The exception carries a date, and it predates the rest.
• Two registrants on the same netname is the fingerprint of a transfer in progress. Blocks move between the operator and the financing entity one record at a time, and the registry shows the midpoint.
• The shared handle means two AS numbers claim the same name in the inventory. Handles are not unique, so a lookup by name can land on either.
