About this network

FIBERX is the network of FiberX, a Puerto Rican fibre-optic operator based in the Metro Office Park in Guaynabo, near San Juan.

What it's used for

• Broadband and fibre services across Puerto Rico for residential and commercial subscribers — FTTH/FTTB, metro Ethernet, VoIP and managed connectivity.
• Colocation and cloud connectivity from FiberX's own Guaynabo data centre.
• Announces a modest footprint of about 4,900 IPv4 addresses along with a /32 of IPv6.

Notable

• This is an island carrier: FiberX operates its own fibre and wireless plant linking Puerto Rico to the mainland United States and onward, so the ASN is one of the handful that actually originate Puerto Rican eyeball traffic.
• The address space mixes a /20 with several scattered /24s, reflecting a network that grew by acquiring space piecemeal rather than receiving one large early allocation.

Interesting

• The ARIN record for both the organisation and the AS number is recent: this low number was reissued to a modern operator, and carries no early-internet history despite sitting in the 6000s.
