That is really challenging task. I am tempted to give you an (allegedly) easy solution at first - Network management, network discovery, SNMP, MIB and WMI browsers, NetBIOS and port scanner - "NetworkView is an ultra compact network discovery and management tool for Windows".
However, if that's not an option, do you really have to stick with the RIP and all those low-level programming ? I would suggest something like combination of traceroute, ping, SNMP and DNS queries. Is that an option ?

NAME
devdiscover - Performs SNMP discovery and generates Torrus XML configuration file. SYNOPSIS
torrus devdiscover [--in=XMLFILE] [options...] [XMLFILES] DESCRIPTION
devdiscover performs SNMP discovery using the XMLFILE for the discovery instructions. It generates a corresponding Torrus XML configuration file. See Torrus SNMP Discovery User Guide for details. The generic input file, or device discovery XML (DDX), may be generated by the genddx utility, and then edited and maintained manually. Multiple input files may be specified by several instances of --in option, or simply as arguments. Input file name is searched in the current directory, and then in /etc/torrus/discovery/. OPTIONS
--mkdir Creates "data-dir" directories. --limit=REGEXP Limits the discovery to the output files matching the regular expression REGEXP. --forcebundle With this option enabled, "devdiscover" will write the bundle file even if some of the bundle members were not created because of errors. --fallback=INTEGER Requires --forcebundle. In case if an SNMP device is not available, the bundle file will include an older version of the XML output file, provided that it exists and it is not older than the specified number of days. --threads=INTEGER If the threads are enabled in the local Perl, this option determins how many parallel discovery threads are to be executed. The discovery jobs are distributed per output files, thus it makes sence to use threads only when there are many output files defined in a single DDX file. --verbose Prints extra information. --debug Prints debugging information. --snmpdebug Prints SNMP protocol details FILES
