Website Blacklist Checker — Malware & Spam DNSBL Scan
Query malware-oriented DNSBL zones for website IPv4 or domain with infrastructure context
How to Use This Tool
- Enter the website hosting IPv4 or domain name.
- Domains resolve to their current A record IPv4 before scanning.
- Parallel DNSBL queries run against primary and extended malware-oriented zones.
- Listed zones are tagged; malwareListHits filters spam and exploit-oriented list names.
- Geolocation adds hosting, VPN, proxy, org, and country context for the resolved IP.
- Review malwareListed, lists array, recommendation, and infrastructure flags.
About This Tool
Compromised websites, phishing pages, and spam relays often appear on DNS-based blocklists before traditional antivirus catches them. Security teams investigating a reported website need fast blacklist context on the hosting IP or resolved domain address. VSPIC website blacklist checker calls the malware-ip action — resolving domains to IPv4 when needed — then queries multiple DNSBL zones with emphasis on malware and spam publishers including Spamhaus, DroneBL, Backscatterer, and Barracuda patterns, surfacing malwareListHits separately from general listings.
Results include query, ip, resolvedFrom, malwareListed boolean, listedCount, lists array, malwareListHits names, hosting, proxy, vpn flags, org, country, summary, and recommendation text. This page frames website blacklist SEO language while the backend matches malware-ip-checker — focused on DNSBL malware and spam hits without composite fraud scoring.
Common use cases
- •Inspect HTTP headers and user-agent strings
- •Analyze email headers for phishing investigation
- •Generate strong passwords for staging environments
Why use VSPIC for ?
- Malware-focused DNSBL hits highlighted separately from all listings.
- Accepts IPv4 or domain with automatic DNS resolution.
- Hosting, VPN, and proxy flags explain anonymizer or server context.
- Per-list breakdown with query hostnames for delisting tickets.
- Plain-language summary and remediation recommendation text.
- Free instant lookup — no account required.
Website IP blacklist versus domain DNSBL
IP blocklists query reversed IPv4 octets — they answer whether the hosting address sent spam or hosted abuse. Domain blocklists query hostname strings on DBL URIBL ZRD — independent of which IP currently serves the site. Website blacklist checker focuses on IP-oriented malware and spam DNSBL via malware-ip action.
Run domain-blacklist-checker on the website hostname when mail filters or URI blocklists are the concern. Run this tool on hosting IP when infrastructure abuse signals matter.
MalwareListHits versus full list results
The lists array shows every DNSBL zone queried and whether each returned a listing. malwareListHits narrows that to zones whose names match malware and spam oriented publishers. malwareListed true warrants urgent website incident investigation.
listedCount greater than zero with malwareListed false still deserves review — some legitimate mail servers carry historical spam listings unrelated to current website compromise.
Domain input and resolvedFrom metadata
Paste a website hostname when logs contain a domain rather than numeric address. We resolve the current A record IPv4 and show resolvedFrom linking the original query to the scanned address. CDN front domains may resolve to edge infrastructure whose listing status differs from your origin server.
When investigating a specific origin, prefer direct IPv4 input if you already know the address from server logs.
Hosting VPN and proxy context fields
Compromised websites cluster on shared hosting and bulletproof providers, but legitimate SaaS also runs on hosting networks. hosting true indicates datacenter allocation — not guilt by association. vpn and proxy true suggest traffic may originate through anonymizer exits.
Combine infrastructure flags with listing data before blocking user traffic solely on hosting classification.
When to run a website blacklist check
Run after users report blocked website access citing blocklist rejection, during incident response on suspected defaced sites, before allowlisting vendor website egress IPs, and when search console or safe browsing warnings appear.
Schedule periodic checks on production web origin addresses. Listings can appear within hours of compromise.
Delisting and remediation workflow
Recommendation text nudges listed addresses toward abuse investigation, patching, and delisting procedures. Fix compromised CMS plugins, close open relays, and remove malware before requesting delisting from each zone maintainer.
Document malwareListHits names in tickets when opening hosting provider abuse cases.
Relationship to malware-ip-checker
Both pages call action malware-ip with identical JSON. malware-ip-checker targets malware blacklist SEO; website-blacklist-checker targets operators searching website blacklist terminology. API action and fields are the same.
Cross-link threat-intelligence-lookup when you need aggregated Spamhaus and fraud score context beyond raw DNSBL detail.
API action malware-ip
GET /ip-tools/api/extended?action=malware-ip&query=example.com or query=8.8.8.8. Parse malwareListed, malwareListHits, lists, hosting, vpn, proxy. Cache briefly — DNSBL status changes hourly during campaigns.
Rate limits protect upstream DNS resolvers — batch internal scans with delays.
Privacy and responsible use
Lookups query public DNSBL zones for addresses you submit. Check only IPs and domains you own or are authorized to investigate.
DNSBL listing is an abuse signal, not legal proof of criminal activity.
Important notes & limitations
- DNSBL results are point-in-time DNS answers — not proof of active infection.
- Listing on one zone does not guarantee malicious intent — investigate before blocking.
- Private and bogon addresses cannot be meaningfully checked on public lists.
- Does not check domain URI blocklists DBL URIBL — use domain-blacklist-checker.
- IPv6-only websites require an IPv4 A record or direct IPv4 input.
