ipv6 Configuration for IPV6

[Manas Lad]

I just noticed one term called "IPV6". I'm wondering what actually it is. What are its advantages? and also disadvantages. If it's beneficial please help me out to configure it. Like do I need a Static IP from my ISP or Dynamic IP will do? Well my Router has IPV6 support as it shows option to enable IPV6. But still I'm afraid to move on......

Advantages: You technically wouldnt have to NAT as much compared to ipv4 and thus it can reduce latency.

Disadvantages: much more complicated IP addresses.

 

If you are actually getting an ipv6 connection then your modem and router most likely already gives you ipv6. I am not sure what makes you afraid of ipv6, nor that is necessary.

how do I know whether i'm getting an ipv6 connection.

and sorry its not the modem ipv6 supported its my router ipv6 supported. i have no idea whether i am given ipv6 or not.

You won't notice any difference. If your ISP provides IPv6 to you it will be enabled on the router they gave you, and will run alongside IPv4.

but i dont know whether i am provided with ipv6. is there any way to know it?

Rule of thumb with IPv6, if you need to ask about it, you don't need it.  Absolutely not worth worrying about right now.

as mentioned above, it reduces latency. but then can i not use ipv4 and ipv6 simultaneously?

IPv6 does not reduce latency by any noticeable amount, the only time it can is if there is (for some stupid reason) a different/better path for IPv6 traffic compared to IPv4 which is almost never the case. You can 1000% do IPv4 + IPv6 on the same network, it's called dual-stack and it's what most of the world uses and will probably continue to use for many years to come until IPv6 is rolled out everywhere.

then what could be the benefits of dual stack? like i only will be able to launch ipv4 and ipv6 sites? i am asking because i want to know about it. and i am pretty sure help will be provided here at LTT. so please do tell me a bit more about ipv6

Dual stack allows the access of IPv4 and IPv6 sites giving you the best of both. By default in most operating systems IPv6 is preferred and will be attempted first if a site supports both but if a site doesn't have an IPv6 address then you'll fall back to IPv4, usually in under a second or two and this happens when there is an issue with IPv6 causing a fallback, otherwise in no time at all since the DNS records only point to IPv4 addresses then the OS will just use IPv4 to access the site.

 

Realistically 95% of the world is dual stack or IPv4 only so unless you're accessing IPv6 only sites then I wouldn't worry about enabling it right now. I mean you can enable it and worst case nothing happens your router just doesn't get an IPv6 prefix/address.

 

Edit:

Almost all home users get dynamic IPv6 but it's different than IPv4 in that with IPv6 you're given a block of public addresses.

so its no harm enabling it without knowing whether i'm being provided a ipv6 connection by my ISP?
