On a device connected to a router (ie - a PC), is it possible for that device to request information from that router? Ideally, I would want to detect my router's make and model by making some kind of request to the router itself. I'd want the PC to be able to make a GET request to it or something along those lines, and find out information about the type of router being used.

Is this kind of thing possible?

There are several technologies available:

  • SNMP (Simple Network Management Protocol): Most business routers support it, very few home routers do.
  • UPnP (Universal Plug-n-Play): Many home routers support it, very few business routers do.

Both these protocols have means to get a make/model of a router, but it's going to be more complex than just a HTTP GET request. You'll need to use specialized libraries to tools to get that info.

If SNMP is enabled, though, snmpwalk -v 2c -c "public" $ROUTER_ADDR SNMPv2-MIB::sysDescr might work (where public is the default SNMP community name) – grawity Jan 20 at 23:57
