Generally anything inside the customer premise (including wiring) is the customer’s responsibility. If your coax runs across a fluorescent light fixture, that’s on you. If your coax is RG59, it’s on you to replace with RG6 quad shield. Maybe the cable operator will work with you, maybe not. I’

Thanks Blake, As I understand it all that stuff is on the "cable provider" side of the CPE and (within reason) it's up to the provider to deal with the signals arriving on the cable side of the modem. i.e. if it was a blower or something in our suite that was causing RF interference, the provider

If then industry still hasn't adopted v6 full in 25 years maybe it's v6 that should be given up it, that it clearly wasn't what customers wanted. Perhaps we should should have a small group working on the next iteration. -jim On Tue, Mar 29, 2022, 5:54 PM Jacques Latour wrote: > So, in 25, 50 o

So, in 25, 50 or 100 years from now, are we still going to be dual stack IPv4/IPv6? When are we going to give up on IPv4? People can run IPv4 all they want inside their networks for 1000s of years. What will it take to be IPv6 only? 😊 From: NANOG On Behalf Of Owen DeLong via NANOG Sent: March

Just to be clear Josh, I'm not insulting him. I find the situation extremely difficult to believe based on my (possibly incorrect) understanding of how PoE works and very (very!) basic knowledge of things like RF interference—especially when it comes to Cable networks. I mean, the call literally

Submit an Internet draft, same as any other IP related enhancement gets introduced. What you’re really complaining about is that it’s been virtually impossible to gain consensus to move anything IPv4 related forward in the IETF since at least 2015. Well… It’s a consensus process. If your idea

Just because there is a small code snippet you found that prevents casting 240/4 as unicast on an interface doesn’t mean that removing that code will magically make 240/4 usable in the entire stack. It’s also important to note that there are at least a dozen IPv4 stacks in common use with diffe
