ipaddr = 192.0.2/24Configuration ip address Data Type
The ip address data type contains IP addresses and netmasks. Both
numerical IP addresses and host names are allowed.

Note
|
Relying on DNS is problematic.
We strongly recommend using numerical IP addresses instead of host
names. When a host name is used, the server has to perform a DNS
lookup. If the DNS lookup fails or times out, the server will be
unable to start, or may be blocked at run-time. Using numerical IP
addresses means that the server will always be able to run.

The configuration directives which take IP addresses and host names follow a fixed naming scheme, as given below.
| Name | Description |
|---|---|
ipaddr |
IP address. Can be IPv4 or IPv6. If given a hostname, the first IPv4 address for that hostname is used. |
ipv4addr |
IPv4 address. If given a hostname, the hostname must resolve to an IPv4 address. |
ipv6addr |
IPv6 address. If given a hostname, the hostname must resolve to an IPv6 address. |
host |
A hostname, as with |
server |
A hostname, as with |
In some cases (e.g. with clients), an IP address network and mask can be used.
