Summary
ZCorum
isp legacy
Registered historically under the handle AMERICA and now named ZCORUM, this is the network of ZCorum, a Georgia company that provides managed broadband services, wholesale internet, and diagnostics to independent cable, telco, municipal, and wireless ISPs.
What it's used for
- Wholesale and managed internet services delivered on behalf of small broadband providers. ZCorum supplies the internet side — transit, addressing, email, DNS, and diagnostics — so that small operators do not have to build it themselves.
- Because of that model, the address space largely ends up on the subscriber connections of ZCorum's partner ISPs rather than on ZCorum's own machines.
Notable
- Effectively eyeball address space at one remove: an IP here is likely a broadband subscriber of some small cable or telco operator, even though the registry names neither that operator nor the subscriber.
- ARIN's organisation record was refreshed recently and reads "Rayvion LLC DBA ZCORUM", while the ASN registration itself dates to 1995.
Interesting
- The old
AMERICAhandle is a direct fossil of the company's origins. ZCorum started as an Atlanta bulletin-board system in 1992 and began selling internet access in 1995 under the name America.net, which is exactly when this AS number was registered — the handle has outlived the brand by three decades. - ZCorum was acquired by ISPN in early 2026, continuing a long run of consolidation among the companies that serve small broadband operators.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
