It’ll be very intersting to see if this is enough to push ISPs to adopt IPv6 en masse, or they’ll keep dragging their feet and use nasty hacks like CG-NAT to avoid it.
- jarfil 7y agoThe more ISPs migrate to IPv6 and CG-NAT, the more free IPv4 addresses for everyone else. Wich means the migration will take a really long time. Also the only way to reach an IPv6 target from a IPv4 source is through a CG-NAT, so dual stack IPv6+CG-NAT deployments should be the norm for many years to come.
- mikl 7y ago> dual stack IPv6+CG-NAT deployments should be the norm for many years to come One can hope. I wouldn’t be too surprised if some ISPs try to deploy just CG-NAT and punt on IPv6 deployment as long as they can.
- tambre 7y agoSupporting IPv6 natively would be cheaper as they'd need to invest less in NAT capacity.
- pilif 7y agoThey will more than make up the difference by increasing the rent for the public IPv4 addresses they got when they were still available.
- icebraining 7y agoYeah, but it's not like offering IPv6 prevents those rents, so why waste that money on NAT capacity if they can pocket it instead?
- pilif 7y agoOnce IPv6 is available widely enough, prices for IPv4 addresses will plummet because there is a nearly unlimited amount of IPv6 addresses available for much cheaper or free
- oarsinsync 7y ago> The more ISPs migrate to IPv6 and CG-NAT, the more free IPv4 addresses for everyone else. Uhhh, they're not returning their IPv4 addresses to any kind of free pool. Those IPs that they have allocated remain with them.
- the_mitsuhiko 7y agoIf they can make money selling them I don’t see that happening.
- oarsinsync 7y agoCurrent cost of an IPv4 address: $20 Value of product that can be sold per IP address: $5 - $1000/month. Having worked in an organisation that had millions of addresses, we opted to carry on having a long term sustainable business over selling our IPs for short term gains. Eventually the addressable market on IPv6 will reach a critical mass. At that point, the value of IPv4 will become relevant to niche markets only.
- mercora 7y agoIn Germany i see most ISPs adopting IPv6 by using DS-Lite[0] which is basically handing out only IPv6 addresses and using CGNAT for IPv4 connectivity by mapping IPv4 addresses into IPv6 address space on the CPE. I don't like that at all as it makes you practically unreachable from the IPv4 address space. In order to get IPv4 addresses you often have to convince them on the phone and describe your use case. When you've done that you will get IPv4 address but no IPv6 addresses anymore. I have no idea why they seem to be so reluctant to a true Dual-Stack solution....
