About this network

The AS handle BLU is held by BLU Fibre Networks inc.

What it's used for

• The address space carries a mix of legacy and current netnames, including CSTD (registrant CTAL), UP-NETBLOCK (registrant UPTele Inc.), BLUFIBRE-CGNT-NET-7, and BLUFIBRE-NETBLOCK-02 (registrant BLU Fibre Networks inc.), indicating a consolidation of multiple predecessor networks.
• With 29,696 IPv4 addresses announced across 36 prefixes and only 10 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.
• As a regional ISP deploying its own fibre infrastructure, the traffic consists of residential and business subscriber Internet, Voice, and IT services.

Notable

• Registrants vary across the inventory, with CTAL, UPTele Inc., and Fibre Argenteuil appearing alongside BLU Fibre Networks inc., reflecting historical acquisitions or leased space.
• The inventory includes diverse prefix blocks such as 23.227.208.0/21 and 116.214.112.0/21, showing a fragmented address space typical of an ISP that has grown through mergers.
