AS5666 — NET-CPRK - Speedcast Communications, Inc

AS5666 announces 2 IPv4 prefixes covering 512 addresses and 0 IPv6 prefixes.

About this network

NET-CPRK is held by Speedcast Communications, a remote-communications provider headquartered in Houston, Texas. The handle is a leftover from CapRock Communications, the satellite operator Speedcast acquired from Harris Corporation in a deal that closed at the start of 2017.

What it's used for

• Supporting Speedcast's managed satellite and remote connectivity services, which link ships, offshore rigs, and other isolated sites back to corporate networks.

Notable

• Very little address space for such a low AS number: two /24s, around 512 addresses. The company's business is selling connectivity over satellite capacity, not holding IPv4.
• One of the two prefixes sits in APNIC-region space, consistent with a provider whose maritime and energy customers operate globally.

Interesting

• The CPRK handle outlived two owners — CapRock was bought by Harris in 2010 and sold on to Speedcast in 2017, but the registry still carries the original abbreviation.
