I have a 11year old modem. However from my knowledge it isn't giving me problems.
I ran an ipv6 test I got "10/10" for for your IPv4 stability and readiness and 0/10 for IPv6. I then tried running it w/o my router wondering if that was a problem and i got 7/10, 0/10 to my surprise.
Anyways it says "Your DNS server (possibly run by your ISP) appears to have IPv6 Internet access" on both runs so i am wondering, is my modem the problem? I know my 'new' router (i think its a 4yr model but apparently solid) doesnt support it with current firmware and my ISP does support ipv6. I cant use ipv6 cause of my router and i might have to request ipv6 support from my ISP but before i do does modems affect it?

These days, most consumer "modems" are in fact routers with additional DSL or cable ports. At least in the case of ADSL, the "modem" performs such functions as obtaining an IPv4 address from my ISP through either DHCP or PPP(oE|oA), distributing addresses to my LAN, and finally publishing management functions over HTTP, Telnet and SNMP.
To use native (ISP-provided) IPv6, the router must obtain an IPv6 address for itself and correctly forward IPv6 packets between your LAN and the ISP. (I'm not entirely sure if ICMPv6 Router Advertisements are forwarded as well, or if the router is supposed to generate them itself – I'm guessing the latter.)
Note: I do not have an IPv6-capable 'modem' here. I'm very likely to be wrong.
