IP Binding¶
On this page
Overview¶
MongoDB binaries, mongod and mongos, bind to
localhost by default. If the net.ipv6 configuration file
setting or the --ipv6 command line option is set for the binary,
the binary additionally binds to the localhost IPv6 address.
Considerations¶
Warning
Make sure that your mongod and mongos
instances are only accessible on trusted networks. If your system
has more than one network interface, bind MongoDB programs to the
private or internal network interface.
If the net.ipv6 configuration file setting or the --ipv6
command line option is set for the binary, the binary additionally
binds to the localhost IPv6 address.
To bind to all IPv4 addresses, you can specify the bind ip address of
0.0.0.0. To bind to all IPv4 and IPv6 addresses, you can specify
the bind ip address of ::,0.0.0.0 or alternatively, use the new
net.bindIpAll setting or the new command-line option
--bind_ip_all.
