Residential ARIN
Summary
SumoFiber
isp legacy
Autonomous System 4226 (SUMOFIBER) belongs to SumoFiber, an independent internet service provider headquartered in Bountiful, Utah.
What it's used for
- Residential and small-business fiber internet, plus TV and voice service.
- SumoFiber sells service over open-access municipal fiber networks such as UTOPIA Fiber, where the city or authority owns the physical fiber and the ISP provides the connectivity, support, and billing.
Notable
- This is eyeball address space. IPs here are subscriber homes and small offices, so geolocation tends to be meaningful at the city level.
Interesting
- The AS number is low, but the current ARIN registration is recent: the number was reissued to SumoFiber rather than held from the early internet. The company itself was founded in 2011.

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: 440 networks and 1,773 prefixes, as published 2026-10-13. 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.
