Ugh.  With the "all gear" in there, this is definitely wrong :-) - slap him.

 - all smaller boxes do IPv4 and IPv6 (both!) in software

 - the 6500/7600 do IPv6 in software on Sup1/Sup2, and in hardware on 
   Sup720 and RSP720

 - some of the cat4000-family devices do IPv4 in hardware and IPv6 in
   software (we have no 4k, so others will help clarify that)

 - the 3750/3560 switches are a bit limited regarding IPv6 features, but as
   far as I remember, they do IPv6 in hardware as well

 - the GSRs do IPv6 in software on some of the older line cards, and in
   hardware on the more recent line cards (I have no GSRs, so I can't say
   for sure which ones are which, but E0 is certainly "software" and E3/E4
   should be "hardware")

 - CRS-1 does everything in hardware

 - ASR1k does everything in hardware (if it can do it at all)

 - no idea about N5k and N7k - I'd say "if it does IPv6, it's hardware"
   but I'm not sure if IPv6 is there yet
