Bind Splunk to an IP

You can force Splunk to bind its ports to a specified IP address. By default, Splunk will bind to the IP address, meaning all available IP addresses.

Changing Splunk's bind IP only applies to the Splunk daemon (splunkd), which listens on:

  • TCP port 8089 (by default)
  • any port that has been configured as for:
    • SplunkTCP inputs
    • TCP or UDP inputs

To bind the Splunk Web process (splunkweb) to a specific IP, use the server.socket_host setting in web.conf.


To make this a temporary change, set the environment variable SPLUNK_BINDIP=<ipaddress> before starting Splunk.


If you want this to be a permanent change in your working environment, modify $SPLUNK_HOME/etc/splunk-launch.conf to include the SPLUNK_BINDIP attribute and <ipaddress> value. For example, to bind Splunk ports to (for local loopback only), splunk-launch.conf should read:

# Modify the following line to suit the location of your Splunk install.
# If unset, Splunk will use the parent of the directory this configuration
# file was found in
# SPLUNK_HOME=/opt/splunk

Important: The mgmtHostPort attribute in web.conf has a default value of Therefore, if you change SPLUNK_BINDIP to any value besides, you must also change mgmtHostPort to use the same IP address. For example, if you make this change in splunk-launch.conf:


you must also make this change in web.conf (assuming the management port is 8089):


See web.conf for more information on the mgmtHostPort attribute.

IPv6 considerations

Starting in version 4.3, the web.conf mgmtHostPort setting has been extended to allow it to take IPv6 addresses if they are enclosed in square brackets. Therefore, if you configure splunkd to only listen on IPv6 (via the setting in server.conf described in "Configure Splunk for IPv6" in this manual), you must change this from to [::1]:8089.
