Individual-IP results
These lists associate the queried address or host with their own observed spam, proxy, compromise, brute-force or abuse criteria. Providers use different evidence and expiry rules.
Reputation tools
Check several reputation lists without treating one list as a verdict.
Look up a public IPv4 address or hostname across independently operated DNSBLs and see whether a result applies to the IP itself, its network allocation, or its ASN.

Reputation result
Read the result
A listing is a signal, not a conviction.
Allocation results
A network-level result can apply because other addresses in the surrounding allocation have poor reputation. It does not prove this exact IP generated the activity.
ASN-wide results
An ASN listing is broader still. Large hosting networks can create collateral results that should be investigated separately from an individual-IP listing.
No listings observed
That means only that the enabled providers did not return a listing at check time. It is not a universal reputation score or an inbox-placement guarantee.
Enabled sources
Seven list views from five independent operators.
The checker currently uses DroneBL, the Passive Spam Block List, blocklist.de, InterServer RBL, and UCEPROTECT Levels 1–3. UCEPROTECT Level 2 is labelled network/allocation scope and Level 3 is labelled ASN scope.
Spamhaus public mirrors are intentionally not queried by this commercial public checker because their current free public-mirror terms do not permit this use. DotMoose will only add a keyed/licensed source after confirming its terms allow a public lookup product.
Results are cached for 15 minutes and uncached reputation scans are capped daily to reduce third-party load and abuse.

Removal
Fix the reason first.
If a provider lists an address, read that provider's returned detail and current removal documentation. Many lists expire automatically or use free/operator appeal paths. Do not pay for expedited removal simply because a paid option is offered, and do not request removal before the underlying abuse, compromise, identity or provider-reputation issue is understood.
