  • It's easier to remember the IPs of good DNSes, too.

  • But DNS rarely break. The meme about it beeing DNS's fault is more often then not just a symptom of the complexity of IPv4 NAT problem.

    If i should guesstimate i think atleast 95% of the dns issues i have ever seen, are just confusion of what dns views they are in. confusion of inside and outside nat records. And forgetting to configure the inside when doing the outside or vice verca. DNS is very robust and stable when you can get rid of that complexity.

    That beeing said, there are people that insist on obscurity beeing security (sigh) and want to keep doing dns views when using IPv6. But even then things are much easier when the result would be the same in either view.

  • I assume the normal fear of unknown things. It is hard to hate ipv6 once you have equivalent competence in ipv4 and ipv6.

  • I felt dirty! and broke so much shit when i had to implement NAT on networks in the mid 90's. Nowdays with ipv6 and getting rid of NAT is much more liberating. The difference is staggering!

    • you do not need NAT any longer, firewall is the security, just like on ipv4, just less obscurity.
    • you do not need dns views, to workaround NAT any more
    • you do not need hairpin NAT to workaround NAT any more
    • you do not need to renumber to resize a network. they are always /64, and the answer to how many hosts can it fit is: ALL of them!
    • many ALG's will be unnecessary since there is not NAT.
    • vpn's are easier, since it can be the same address both inside and outside the vpn, the firewall (or host even) enforces the encryption.
    • vpn's are MUCH easier since you will have less rfc1918 collisions due to some other network using the rfc1918 of the vpn's network
    • vpn's are MUCH MUCH easier since you will have less rfc1918 collisions due to you using the rfc1918 of the vpn partner network, to 1:1 nat a previous vpn network you collided with some months ago... ARGH!!!
    • vpn are generally less required, heck i swear 95% of the time the VPN are just to workaround the NAT problem and the data is pointlessly double or triple encrypted.
    • you can make more granular firewall rules (eg the spesific host, or network of the source address, instead of the whole enterprise's public ip) this is real tangible improved security, where any random machine in a network you do not control. do not automatically have openings into your own network.
    • firewall objects can if it is suited easily use and depend on FQDN DNS objects when allowing traffic. reducing the need of coordinating firewall object ip address changes between 15 companies.
    • firewall rules are easier, more readable, and much more predictable how they will work. All the hairpin nat, public to private nat, private to public nat for a thing that need a different public ip, 1:1 nat for a separate zone, NAT to a vpn or 50 (where 10 of them are 1:1 nat due to collisions, making you require 4 dns views of the same ip space!! ) very quickly gets messy and unreadable. this is probably the largest security benefit. just to reduce the complexity.
    • much easier to get people to use dns, since nobody wants to remember ipv6 addresses :D
    • nibbles in the ipv6 address can have meanings you assign to them, making the networks and structure both easy to remember and logically structured.
    • aggregating routes becomes very easy if you design your network that way.
    • firewall policies can become easier if you design your network that way.
    • your routing tables is leaner and easier, and of a better consistency. We have 1 large public ipv6 prefix, but 25ish ipv4 prefixes of all kinds of various sizes.
    • no need to spend $$ to buy even more ipv4 prefixes.
    • no need to have spent hundreds of $$ on a new ipv4 prefix only to be unable to use them for over a year because you need to sanitize the addresses from all the reputation filters. and constantly hound geo ip database providers to update the new country of the prefix. (i am bitter,, can you tell..)
    • did i mention no need to renumber since you need to grow the /24 to /23 due to to many hosts in a network ?
    • did i mention no need to renumber 2 /24's to /25's to make space for that larger /23.
    • you do not even need any ipv4 addresses any more, use a public NAT64 service, for outgoing. and for incoming just use one of the many free public ipv4 to ipv6 proxies for your services online. for a homelab i really like http://v4-frontend.netiter.com/ (go support them) But most large business l networks use cloudflare, or akamai
    • since you do not need your ipv4 address space any more, you can ~~sell them for a profit $$$ ~~ return them to the RIR and give some address space to one of the thousands of companies struggling because they do not have any IPv4 : https://www.ripe.net/manage-ips-and-asns/ipv4/ipv4-waiting-list/
    • much lower latency on ipv6, since you do not go across a cloud based ipv4 to ipv6 proxy in order to reach the service ;)

    Now the greatest and best effect of ipv6 is none of the above. It is that with ipv6 we have a slim hope of reclaiming some of what made the Internet GREAT in the first place. When we all stood on equal footing. Anyone could host their own service. Now we are all vassals of the large companies that have made the common person into a CGNAT4444 using consumer mindlessly lapping up what the large company providers sees fit to provide us. with no way to even try to be a real and true part of the Internet. Fight the companies that want to make you a eyeball in their statistic, Set up your own IPv6 service on the Internet today !

  • Never been an issue for me debian+kde+steam it started right up the first time i tried. No tweaking needed.

  • China block much of the internet so who knows with china. Do not know if anyone have real china numbers of IPv6 deployment. They also had their own "IPv9" that was rumored some years ago that may or may not have been used internally.

  • Not much choise i guess. Usa and europe grabbed the majority of available ipv4 space. Asia got a bit. And only scraps and leftovers for africa and latin america.

  • You do as well, if you run any operating system newer then the last 10 years.

  • That should simply not be allowed. Cgnat for ipv4 is fine if they also provide proper ipv6

  • February looks like it is gunning for someone... what a worryingly consistent increase.

  • Maybe we can get good IPv6 support now

    Jump

  • Yes it does take extra work. Problem is often that that work was done in the past when isp implemented their ipv4 metodology. And instead of using the ipv6 rollout as a chance to improve their design and operations. They just add ipv6 into their ipv4 design and methodology. They encumber their ipv6 rollout with their decades of technical debt and cruft they have normalized in their ipv4 world. And it will makes things harder for themselfs when trying to turn off ipv4 in the core.

  • Goverments (depending on juristiction) have laws requiering isp's to keep track of cgnat port combos. So not only is there no privacy from ipv4 cgnat. Now the isp must also spend a lot of money on the nat state tracking database.If you need that kind of privacy, use a vpn and the tor onion network.

  • I am 50/50 between incompetence. Or so they can keep on charging extra for a static ip.

  • What anyone mean when they say get rid of dst is to stop the flipflopping.But i guess you are technically right. Witch i have heard is the best kind of right. Even if very pedantic ;)

  • I would not mind if americans used whatever. As long as anything exported from america always!! used metric. As it is now we need 2 complete sets of nuts and bolts, pipes and fittings, tools and gizmos, csbles and connectors. Just imagine the space we could save in our shops and storages if we could /2 the requires spare part storage. Not to mention the time and frustration avoided when doing basically anything on almost anything.

  • Same i have friends that have crashed perhaps once or twice a week on windows.But never been an issue for me on linux. Only had it for the last month tho. Could be an older fixed issue as well.
