So don't CGNat? Buy IPv4 addresses at auction?
Buy IPv4 addresses until CGN is cheaper. If a customer has to call, and you have to assign an IPv4 address, you have to recover the cost of that call and address. While ((CostOfCall + CostOfAddress)*NumberOfCalls) > (CostOfAddress*NumberOfNewCustomers):
BuyAddresses(NumberOfNewCustomers)Meanwhile, deploy IPv6, and move toward IPv4aaS, probably 464xlat or MAP, but your religion may vary. That way your "CGN" is an IPv6-IPv4 translator, and that's easier than managing dual-stack.
At the very least, dual-stack your web sites now, so the rest of us can get to it without translation.

He still will need to dual stack and CGNat that.But the flows that can support ipv6, will go ipv6 and not be subject to these abuse triggers.Look, this list has monthly reports from some small network operator hurting their customers with CGN NAT. Meanwhile, the big guys like Comcast / Charter / ATT / Cox have moved onto ipv6.Where does that leave the little guy with CGN?Right here. Screaming into the avoid begging for help. Some special exception.And, me, saying you had 10+ years of not deploying ipv6. Here’s to the next 10 years of you email this list about your own failure to keep up with the times.We will have this discussion again and again. Not sure your customers will stick around, all they know is your CGN space got black listed from yet another service#realtalk On Sep 11, 2018, at 08:54, Ca By <cb.list6 () gmail com <mailto:cb.list6 () gmail com>> wrote:On Mon, Sep 10, 2018 at 9:12 PM Darin Steffl <darin.steffl () mnwifi com <mailto:darin.steffl () mnwifi com>> wrote: Hello, I have a ticket open with OpenDNS about filtering happening on some of our CGNAT IP space where a customer has "claimed" the IP as theirs so other customers using that same IP and OpenDNS are being filtered and not able to access sites that fall under their chosen filter. I have a ticket open from 6 days ago but it's not going anywhere fast. Can someone from OpenDNS contact me or point me to a contact there to help get this resolved? I believe we need to claim our CGNAT IP space so residential users can't claim IP's of their own. Thank you! You should provide your users ipv6, opendns supports ipv6 and likely will not have this issue you see https://www.opendns.com/about/innovations/ipv6/ I am sure it may cost you time / money / effort. But this old thing we call ipv4 is in a death spiral, and it will just get worse and worse for you without ipv6. -- Darin Steffl Minnesota WiFi www.mnwifi.com <http://www.mnwifi.com/> 507-634-WiFi <http://www.facebook.com/minnesotawifi> Like us on Facebook <http://www.facebook.com/minnesotawifi>
