Summary
Frontier Optical Networks (FON)
isp residential eyeball fiber
Frontier Optical Networks (FON) Ltd is a Nairobi-based Kenyan fibre operator providing fixed broadband to homes and businesses.
What it's used for
- Fibre-optic home and business internet in Nairobi and surrounding areas of Kenya.
Notable
- An "eyeball" network: much of this space is end-user broadband on FON's last-mile fibre, not servers.
- FON also does enterprise last-mile, dark-fibre leasing and colocation, so the ASN mixes consumer access with carrier and business services.

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: 436 networks and 1,771 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.
