The <host/> tag

There is some degree of flexibility in how you specify a hostname with the <host/> tag.

You can specify an absolute hostname like this:

<host>conference.yak</host>

You can specify more than one hostname like this:

<host>conference.yak</host>
<host>talk.yak</host>

For example, if this pair of <host/> tags appeared in an instance specification for the Conferencing component, you could address the component instance using either hostname.

You can use a wildcard character to specify all hostnames within a domain, for example:

<host>*.pipetree.com</host>

will match on all hosts with the domain name pipetree.com.

If you want the component instance to receive packets regardless of the hostname, you can specify an empty tag thus:

<host/>
