[mrtg] Does MRTG allow checking what IP is using most of bandwidth?

MRTG will not tell you who (what IP) is using the most bandwidth because that information is likely not available through SNMP, and even if it was, MRTG is not meant to collect and analyze per-ip traffic stats.

If you want that kind of data, you need to investigate using Netflow/Sflow/IPFIX to get it from a nearby router or flow-generating device.

Two places to start are...
the flow-tools-ng project: http://code.google.com/p/flow-tools/
nfdump: http://nfdump.sourceforge.net/
