Summary

Alabama Fiber Network

United States of America · AI-generated

fiber middle-mile nsp regional

ALABAMA-FIBER-NETWORK is operated by Alabama Fiber Network.

What it's used for

  • The address space carries middle-mile fiber infrastructure, with reverse DNS entries pointing to ip.alabamafibernetwork and the netname FUN-4.
  • The network announces 2048 IPv4 addresses and 1 IPv6 prefix, with 23 observed neighbours, indicating a role as a regional network service provider (NSP) rather than a large transit provider.
  • Traffic consists of scalable middle-mile fiber infrastructure, Ethernet, and internet services connecting counties and communities across Alabama.

Notable

  • The registrant Alabama Fiber Network agrees with the announcer, and the netname FUN-4 is consistent with the operator's identity.
  • Alabama Fiber Network is a coalition of electric cooperatives and partners that rebranded to establish a state-of-the-art middle-mile broadband backbone across the state.
  • The inventory consists of a single IPv4 prefix 209.178.216.0/21 and one IPv6 prefix 2602:f9fd::/32.

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: 442 networks and 1,783 prefixes, as published 2026-10-20. 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.
