Namespaces
http://xml.juniper.net/junos/commit-scripts/1.0
SLAX Syntax
var $name = jcs:hostname(expression);
XSLT Syntax
<xsl:variable name="name" select="jcs:hostname(expression)"/>
Release Information
Function introduced in Junos OS Release 9.3.
Description
Return the fully qualified domain name associated with a given IPv4 or IPv6 address. The DNS server must be configured on the device in order to resolve the domain name.
Parameters
expression | — | IPv4 or IPv6 address. |
Return Value
name | — | Hostname associated with the IP address. |
Usage Examples
The following example initializes the variable address with the IP address 10.10.10.1. The $address variable is passed as the argument to the jcs:hostname() function. If the DNS server is configured on the device, the function will resolve the IP address and return the fully qualified domain name, which is stored in the variable host.
var $address = "10.10.10.1"; var $host = jcs:hostname($address);
In XSLT:
<xsl:variable name="address" select="10.10.10.1"> <xsl:variable name="host" select="jcs:hostname($address)"/>
