# bind
## Name
*bind* - overrides the host to which the server should bind.
## Description
Normally, the listener binds to the wildcard host. However, you may want the listener to bind to
another IP instead.
If several addresses are provided, a listener will be open on each of the IP provided.
Each address has to be an IP of one of the interfaces of the host.
## Syntax
~~~ txt
bind ADDRESS ...
~~~
**ADDRESS** is an IP address to bind to.
When several addresses are provided a listener will be opened on each of the addresses.
## Examples
To make your socket accessible only to that machine, bind to IP 127.0.0.1 (localhost):
~~~ corefile
. {
bind 127.0.0.1
}
~~~
To allow processing DNS requests only local host on both IPv4 and IPv6 stacks, use the syntax:
~~~ corefile
. {
bind 127.0.0.1 ::1
}
~~~
If the configuration comes up with several *bind* directives, all addresses are consolidated together:
The following sample is equivalent to the preceding:
~~~ corefile
. {
bind 127.0.0.1
bind ::1
}
~~~
