About Unbound

Unbound is a validating, recursive, and caching DNS resolver.

The C implementation of Unbound is developed and maintained by NLnet Labs. It is based on ideas and algorithms taken from a java prototype developed by Verisign labs, Nominet, Kirei and ep.net.

Unbound is designed as a set of modular components, so that also DNSSEC (secure DNS) validation and stub-resolvers (that do not run as a server, but are linked into an application) are easily possible.

First step, download Unbound ZIP files from:

http://www.unbound.net/downloads/unbound-1.4.12.zip

then extract all files to d://Unbound,

Next step,you must edit next two files so you can let it work fine on windows.

server.conf:

# Unbound configuration file on windows.
# See example.conf for more settings and syntax
server:
    directory: “d:Unbound”
    # file to read root hints from.
    # get one from ftp://FTP.INTERNIC.NET/domain/named.cache
    root-hints: “named.cache”

    # the log file, “” means log to stderr.
    # Use of this option sets use-syslog to “no”.
    logfile: “unbound.log”

    # verbosity level 0-4 of logging
    verbosity: 0

    # on Windows, this setting makes reports go into the Application log
    # found in ControlPanels - System tasks - Logs
    use-syslog: no

    # if yes, perform prefetching of almost expired message cache entries.
    prefetch: yes

    # Enable IPv4, “yes” or “no”.
    do-ip4: yes

    # Enable IPv6, “yes” or “no”.
    do-ip6: no

    # Enable UDP, “yes” or “no”.
    do-udp: yes

    # Enable TCP, “yes” or “no”.
    do-tcp: yes

Unbound.reg:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINESOFTWAREUnbound]
“CronAction”=”"D:Unboundanchor-update.exe" “
“InstallLocation”=”D:Unbound”
“ConfigFile”=”D:Unboundservice.conf”
“CronTime”=dword:00015180
“Start Menu Folder”=”Unbound”

Now you can run unbound-service-install.exe ,after this you will get a high performance local DNS resolver with validating, recursive, and caching(memory) function.
