The Brukalai.lt Light DNSBL blacklist is a real-time DNS blocklist for IP addresses. Brukalai.lt describes this Light zone as listing public proxies, botnets, and other abused IPs. This blacklist (or blocklist) is a specialized subset of the wider Brukalai.lt DNSBL data.
Its primary purpose is to help website administrators detect and block malicious bots. This can prevent comment spam, dictionary attacks on login forms, and other automated abuse. From a technical standpoint, it is an IP-based DNSBL with the zone name light.dnsbl.brukalai.lt. A listing is confirmed when the lookup returns an A record such as 127.0.0.2. NXDOMAIN means the queried host is not listed. DNS timeouts, SERVFAIL responses, or refused queries should be treated as inconclusive, not as evidence of a listing.
Who runs Brukalai.lt Light DNSBL blacklist?
This blacklist is operated by Brukalai.lt, an organization based in Lithuania. Brukalai.lt publishes three DNSBL zones: black.dnsbl.brukalai.lt for junk mail filtering, light.dnsbl.brukalai.lt for public proxies, botnets, and abused IPs, and white.dnsbl.brukalai.lt as a whitelist of verified IPs and domains.
Brukalai.lt advises users of its services to combine blocking data with a whitelist or allowlist of reputable and verified senders to reduce false positives.
How to check a Brukalai.lt Light DNSBL listing
Check an IPv4 address by reversing the octets and appending the zone name. For example, 192.0.2.10 becomes 10.2.0.192.light.dnsbl.brukalai.lt. Public DNSBL metadata lists IPv4 support for this Light zone and no IPv6 support.
Example DNSBL lookupBASH
dig 10.2.0.192.light.dnsbl.brukalai.lt A dig 10.2.0.192.light.dnsbl.brukalai.lt TXT # A response such as 127.0.0.2 means listed. # NXDOMAIN means not listed. # SERVFAIL, timeout, or refused means the result is inconclusive.
When a TXT record is present, it can give extra context about the reason for the listing, such as a firewall block, mail attack source, HTTP attack source, SSH attack source, or bot activity. Treat that reason as a starting point for remediation rather than as the full incident report.
How do I get removed and delisted from Brukalai.lt Light DNSBL blacklist?
To request removal from this blocklist, first identify and resolve the issue that caused the listing. This can involve securing a compromised server, removing a virus, fixing bad software, correcting a misconfigured mail server, closing an open proxy, or stopping a spam outbreak. Once you have taken corrective measures, you can request delisting.
The delisting process is manual and requires you to follow specific instructions:
- Email dnsbl@brukalai.lt with your removal request and include a detailed explanation of the actions you have taken to prevent future abuse from your IP address or domain.
- Send the request from a clean mailbox that is not listed on blocklists (blacklists), because a blocked sender has a higher chance of not reaching the Brukalai.lt team.
- Obfuscate the IP address or domain name in the message. For example, write "192(dot)168(dot)1(dot)1" instead of "192.168.1.1".
- Wait for manual review. Brukalai.lt states review usually takes 2 to 3 days, and repeat entries listed three or more times are not removed through the standard path.
What is the impact of being listed on Brukalai.lt Light DNSBL blacklist?
The impact of being on the Brukalai.lt Light DNSBL blacklist is usually low for email deliverability because the Light zone targets public proxies, botnets, and abused IPs used by websites to block bot traffic. A listing is more likely to affect access to forms, login pages, comments, or online services that query this blocklist to stop automated abuse.
It still deserves investigation. A Light listing means the IP address has been associated with malicious activity, and the same abuse source can also affect mail reputation if it is a server that sends email. If a Brukalai listing appears while mail is failing, Suped's DMARC reporting can help you confirm which sources pass SPF, DKIM, and DMARC, then isolate unauthorized sending before you request delisting.
