Summary
IRIS Networks
transit isp legacy
IRISNETWORKS is IRIS Networks, a regional fibre-optic transport carrier headquartered on Commerce Street in Nashville, Tennessee. It sells middle-mile capacity — dark fibre, carrier ethernet, dedicated internet access and wireless backhaul — across Tennessee and the neighbouring states.
What it's used for
Wholesale transit and transport, not eyeball access. The routing shape makes the case on its own: RIS sees only 5 IPv4 prefixes (4,864 addresses) and one IPv6 block, 2607:f920::/32, but 42 observed BGP neighbours. Peer count is the honest role signal here, and forty-plus adjacencies against fewer than five thousand addresses is a carrier signature. An enterprise or a small ISP holding the same amount of address space would peer with a handful of upstreams. IRIS carries other people's traffic and other people's prefixes, so its own originated footprint stays small while its position in the middle of AS paths stays busy.
Notable
Four of the five prefixes are registered to IRIS Networks itself. The fifth, 64.3.212.0/23, registers to Verizon Business under an XOXO-BLK handle — legacy XO Communications space. That is provider-assigned address space carried by the customer's own AS, a routine carrier arrangement, not a sign of leased or brokered inventory.
Interesting
ARIN dates the AS number to 2007, not the early internet. Its low number is an artifact of ARIN reissuing space in this range, and the company's own history reaches back further than the ASN does.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
