Summary
Layer3 Limited
business nsp nigeria fiber
Layer3- is operated by Layer3 Limited, a Nigerian technology solutions provider.
What it's used for
- The address space is registered under the netname
ORG-LL2-AFRINICfor Layer3 Limited, supporting its provision of network infrastructure, fiber internet, and managed IT services. - The AS announces 3072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 14 observed neighbours; this ratio suggests a role focused on serving business customers rather than large-scale residential access or pure transit.
Notable
- Both announced IPv4 prefixes are registered to Layer3 Limited, confirming alignment between the registrant and the AS holder.
- The inventory consists of two distinct IPv4 blocks,
102.164.32.0/21and41.217.204.0/22, alongside a single IPv6 prefix, indicating a focused corporate estate rather than a fragmented or leased address space.

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 1,773 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.
