Summary
Socket Holdings Corporation (Socket Fiber)
isp legacy
AS4581 (SOCKET) belongs to Socket, the Columbia, Missouri independent telecom founded in 1994 and now operating as Socket Fiber. It is one of the state's largest locally owned internet providers.
What it's used for
Broadband access across Missouri. Socket delivers fibre internet to homes in Columbia, Fulton and many rural counties, plus data and voice services to businesses, schools, healthcare and government.
Notable
- Classic eyeball network. The address space is dominated by residential subscriber assignments rather than servers, which is what a ~96k-address ISP footprint in a mostly rural state looks like.
- Socket began as a dial-up and DSL competitor and rebuilt around fibre-to-the-home from the early 2010s onward.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
