According to the press release, "Four companies led by Dutch non-profit NLnet Labs have launched an open source, Linux-compatible DNS (Domain Name System) server. "Unbound," which is also sponsored by VeriSign, Nominet, and Kirei, claims to offer a validating, recursive, and caching DNS server that is faster than the open source DNS mainstay BIND." Yes. Besides OpenDNS, BIND, UltraDNS (Neustar), we now have yet one more option for DNS.
"Since the 1980s, the open source BIND (Berkeley Internet Name Domain) has been the de facto DNS standard in the Unix and Linux worlds. Last year, BIND was updated to version 9, adding support for DNSSEC (DNS Security Extensions), a security enhancement to the DNS protocol that protects against attacks such as DNS cache poisoning. ... DNSSEC support is also a central focus of Unbound. Like BIND, Unbound is released under a BSD license. ... Unbound 1.0 is available for free download under a BSD license from the Unbound site, here. NLnet Labs offers support for Unbound through a bug-tracking system and user mailing lists, and promises to provide two years warning if the company ever decides to cease providing support. Unbound runs on POSIX-based operating systems such as Linux, MacOS X, FreeBSD, and Solaris, says the group."
Unbound was designed to be recursive DNS server. Neustar (under the UltraDNS branch) offers Recursive DNS service for free. (Tell them RAD-INFO sent you!)
