AS13768 — COGECO-PEER1

Network type: hosting

AS13768 announces 393 IPv4 prefixes covering 618,496 addresses and 18 IPv6 prefixes.

About this network

Two addresses in completely different blocks answer with exactly the same hostname.

What it's used for

• A hosting and connectivity provider. 619,008 addresses across 432 IPv4 prefixes, 18 IPv6 prefixes, and 38 observed BGP neighbours.

Notable

• 216.65.32.0 and 66.40.16.0 both answer as host0.maxim.net.
• 216.65.63.255 and 66.40.31.255 both answer as host255.maxim.net.
• The names encode only the final octet, so every block using the scheme produces the same set.
• 216.157.64.0/19 is netname 216-157-0-0-NET and 64.224.192.0/19 is 64-224-0-0-NET, each naming a parent rather than the block itself.
• 5.44.16.0/20 is netname UK-COGECOPEER1-20120522, a country, two brands and a date.
• One registrant appends a role for enforcing the acceptable use policy.

Interesting

• A reverse name that encodes one octet cannot distinguish addresses in different blocks, and here two pairs of addresses prove it: same name, same zone, four separate addresses. Anyone resolving forward from that name gets one answer, and it will be wrong for at least one of them.
• Netnames naming the parent block instead of the assignment make the registry describe a larger range than was actually delegated, which is the opposite of what a netname is for.
• Four brands appear in the reverse names alone, on top of the two in the handle and the several in the registry.
