What is DNS8?
DNS8 is a DNS security service operated by Layer8 that provides DNS-level blocking of malicious domains for ISPs and enterprise customers. Their service filters malicious and phishing domains at the DNS resolver level, before users can establish any connection to a flagged site. DNS8 data is embedded in ISP-level DNS infrastructure, giving their blocklist enormous reach across all connected devices on affected networks.
Why DNS8 flags legitimate domains
- Your domain was identified as hosting or distributing malware
- A phishing page on your domain was reported and confirmed by DNS8's analysis
- Your domain appeared in threat intelligence feeds consumed by DNS8's blocking engine
- Your domain's DNS records or registration patterns matched high-risk infrastructure profiles
- Automated crawling detected suspicious redirects or malicious scripts on your pages
What a listing means for your business
DNS-level blocks are the most complete form of blocking. They prevent any connection to your domain before a browser even sends a request. For users on DNS8-filtered ISP or enterprise networks, your domain simply does not resolve. There is no browser warning, no SSL error, just silence.
How BrandsDefender gets you delisted
We verify that your domain is clean, prepare the evidence DNS8 needs, file the false positive dispute through the right channel and follow up until the flag is removed. No cure, no pay.
Frequently asked questions
Why can't some users reach my site at all, not even getting a warning?
DNS-level blocks prevent your domain from resolving entirely. Affected users receive a connection failure rather than a security warning. DNS8 is one of several DNS security services that operate this way.
Does Layer8 accept delisting requests?
Layer8 processes delisting requests through their security team for false positive cases. Evidence of remediation and site legitimacy is required. Our team manages the submission and monitors for DNS propagation confirmation.
