# 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
|
|
}
|
|
