What is a DNSBL?

A DNS-based Blackhole List (DNSBL, Real-time Blackhole List or RBL), is a means by which an Internet site may publish a list of IP addresses, in a format which can be easily queried by computer programs on the Internet. As the name suggests, the technology is built on top of the Internet DNS or Domain Name System. DNSBLs are chiefly used to publish lists of addresses linked to spamming. Most mail transport agent (mail server) software can be configured to reject or flag messages which have been sent from a site listed on one or more such lists (Source)

We are regularly scanning new proxies that are reported to us and we're also trying to keep updated with the "Tor"-network proxies, a network that forgets that anonymity can be a problem when we are speaking abuse.

Resolving

dnsbl.tornevall.org: Default zone
opm.tornevall.org: Added 1 june 2016 (Deprecation as of 30 june 2013 was reverted)
bl.fraudbl.org: Added 22 june 2016

RBL Bitmasking Data

dnsbl.tornevall.org
1	IP address has been reported (As this bit has no real actual effect and rather is a false positive, it will be deprecated in short) Meaning: The ip has been reported from a third party application, honeypot, but may not necessarily be confirmed by our local sweepers (this is for proxies) As there may be SMTP-servers amongst our hosts, this bit value may be unsafe to use and in the case of SMTP, there is no available confirmation. Deprecating from march 2017
2	IP has been confirmed as working proxy.
4	When FraudBL is used, this mask confirms the host as fraudible (Servers used for phishing, fraud, etc) Active since June 2016
8	Will update soon As this bitvalue has no meaning (since it only flags that nothing happens while trying to connect to it, this will change shape soon (Deprecated: timeout)
16	June 2016: E-Mail spammer This is the former field for failed connections, which there is no interest in Active since June 2016
32	IP is tested and is fully functional but there is a second entry point (meaning this ip is not the same as the one that has been used by the user"), or the address is an exit node in TOR-network
64	IP is marked as "abusive". Primary used to point out spam or attacks through webforms, forum, telnet, etc. Updated since June 2016: When FraudBL is used, this mask are also added, which means that - for example - if there is a phishing case (mail) the bit will be set to over 64 (4+16+64).
128	IP has a different anonymous-state (web-based proxies, like anonymouse, etc)

bl.fraudbl.org

Follows all bitmasks as dnsbl.tornevall.org generates.

wl.tornevall.org - whitelisting system [PLANNED ONLY]
1	This status is set by the auto whitelisting system, after manual inspections
2	This status is set by the webservice removal system
4	This status is set when removal has been made manually, through support

The FraudBL Project

Fraudalent/phishing-tagged e-mail

FraudBL has just been started as a separate project - for the moment you can reach the site at https://fraudbl.org. FraudBL - Explained has been added here at the docs (from fraudbl.org), for your convenience.

FraudBL is a separate project, which lists mail that contains all kinds of phising. However, dnsbl.tornevall.org is covering FraudBL too so you actually don't need to resolve against both domains unless you don't want another scoring on the FraudBL content. Since dnsbl.tornevall.org collects all kinds of spam, the scoring is normally lower rated than the phising mail.

More information about the scoring can be found at DNSBL for Spamfilters.

Project status

We are currently working on a complete migration to a new system. Here, you can find the status of that project.
Older versions from 2006 are following TornevallWEB versioning (1.x-4.x).

Why does the project take time?

The complexity of some of our functions are described in . However, the project is being made on spare time, so if something else happens in the private life of Tornevall, it will get higher priority. However, if there are disruptions in the services, such cases will also have higher priority.
