Hosting ARIN NSP
Summary
Cologix (Net Access)
hosting legacy
COLOGIX — the network of Cologix, Inc., a North American network-neutral
colocation and interconnection company. This particular AS is the former **Net
Access Corporation (NAC)** of Parsippany, New Jersey, which Cologix agreed to
acquire in October 2015; the handle changed, the network did not.
What it's used for
- Colocation, dedicated servers and managed hosting out of Cologix's Northern New Jersey facilities, plus IP transit to the tenants in them.
- Interconnection: Cologix runs carrier-neutral meet-me rooms and exchange fabrics, so this AS peers widely rather than serving eyeballs.
Notable
- Every ARIN block behind it is still named
NAC-NETBLK*and registered to Cologix, Inc., and the reverse DNS that does exist resolves undernac.net— including the deadpanthis.ptr.is.named.in.honor.of.arin.nac.net. - ~55 announced IPv4 prefixes (roughly 430k addresses) with dozens of observed BGP neighbours, plus native IPv6 out of
2001:518::/32. That peer count is the signature of a datacentre and exchange operator, not an access ISP. - Addresses here are servers. There is no subscriber pool in the inventory: no
dsl-,pppoe-ordyn-reverse names anywhere in the space.
Interesting
- The
2001:518::/32allocation is an early one — NAC was routing production IPv6 well before most US hosting providers offered it.
