Remember when I was wrestling with my router last year? I could only get a /64, which is worthless if you've got more than one subnet behind your router. It's perfectly conceivable for an ISP to charge for a /56, not because the should, but because they can. Same thing goes for static vs dynamic. It's not about common sense, it's about making money. BTW, I'm still running v4 only, with four natted subnets.
If I were to use the modem/router as a router, I'd be limited to a /64. But with a separate router, I can get my choice up to a /56. One thing I tried setting up yesterday is a "Unique Local Address" network. ULAs are similar to RFC1918 addresses in that they can be routed, though not over the Internet. I created a /48 prefix by starting with "fd" and adding a 40 bit random number to it. With a 40 bit number, there are about 1.1 trillion /48 prefixes. I just configured pfSense to advertise the network and all IPv6 capable devices can use it, in addition the usual global addresses. The prefix I use is fd48:1a37:2160::/48, but don't tell anyone because it's secret! ;-) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
