AS5666 NET-CPRK - Speedcast Communications, Inc
Unclassified ARIN
Summary
Speedcast Communications
enterprise satellite legacy
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
CPRKhandle 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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 448 networks and 1,851 prefixes, as published 2026-11-04. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
