I'd personally memorize them if you can, but I really doubt there would be a lab question asking you to block them without having them listed. However, as Alexei pointed out, there may be some more basic addresses that could be expected to be known. We never know though, so it's best to memorize as much as possible to be safe.
Another area of memorization that comes to mind are the various EtherTypes (e.g. IPv4 0x0800 etc) and various MAC addresses for things like CDP/DTP/VTP etc. An EtherType reference: http://nmap.org/book/nping-man-ethernet-options.html Jason Sent from my Commodore 64 On Aug 11, 2012, at 4:12 AM, Alexei Monastyrnyi <[email protected]> wrote: > yes, in this light I reckon they would give you a list of bogons should then > ask to filter them. > > I would remember RFC1918 plus some extra test/loopback/link-local networks > > A. > > > On 8/11/2012 8:04 PM, Matt Hill wrote: >> This is pretty much the point I was making.
