Cogent is great if you treat them as a path. I wouldn't use Cogent in place of single homing a service provider though due to how they run their network and the subsequent peering disputes that arise. Don't get me wrong, I like Cogent, they definitely have a good use case, just be cognizant of how

Pretty much this. It's your business model to have your email be deliverable, while it is not my business model that your mail is received. If I get spam outside of obvious cases of receiver issues, I just block. I'm not going to bother to jump through hoops to report issues you should be dealing w

The problem isn't the consumer devices. The problem is most of the open source router software developers don't see ipv6 as a priority, or something even worth "wasting time" on. On Wed, Dec 11, 2013 at 1:57 PM, Leo Bicknell wrote: > > On Dec 11, 2013, at 1:46 PM, "Kinkaid, Kyle" wrote: > > >

Regardless of the carriers, you'll find most ASs on the internet only listen to /48 or larger. So even if you get your prefixes accepted by your provider, don't assume you can get anywhere, or have your packets not fall in to uRPF blackholes randomly without a larger aggregate announcement. -Blake

The better question is are you using RIP or ICMP to set gateways in your network now? If you don't use those now, why is RA a better solution in ipv6? -Blake On Mon, Dec 30, 2013 at 1:20 PM, Ryan Harden wrote: > On Dec 30, 2013, at 12:58 PM, Lee Howard wrote: > > >> > >> > >> 'Rewrite all of

Re: turning on comcast v6

2013-12-31 Thread Blake Dunlap
The reason RIP isn't used to hand out routes is not based on age, or protocol design. It's based on the fact that we don't want host segment routes (usually only default) to be announcement based, because that leads to problems and uncomfortable meetings with VPs. DHCP will happily give out a corre

I'm sorry, but IPv4 DHCP was a wonderful solution to many issues, which are very very difficult in IPv6. RA is a solution looking for an actual problem. That being said, I like having the option of RA, but it is only useful in a very small subset of use cases, many it actually causes issues, instea
