To retrieve server configuration information you'd need to link your
hook library with libkea-dhcpsrv and do something like this:

#include <dhcpsrv/cfg_iface.h>

ConstCfgIfacePtr cfg =  CfgMgr::instance().getCurrentCfg()->getCfgIface();
ElementPtr iface_configuation = cfg->toElement();

The iface_configuration will now hold the conifguration structure you're
looking for.
