<p>Does it make sense to return ipv6 host without square brackets instead of the full value? There is {s.unbracket} transformation if one needs it to remove the brackets:</p>

</ul>
<p>I am thinking from the perspective that host/domain parts of URI variables just return the value as it is, like $rd returns <code>host</code> as it is in <code>sip:user@host</code>.</p>
<p>Maybe you can add another variable like $siptrace(src_hostip) which return bare IP, without brackets for IPv6 case and $siptrace(src_host) will return the full value as it is in <code>proto:host:port</code>.</p>
