Limit increase for IPv6 per instance possible?

0

Hi there,
I am looking for a way to increase the limit on IPv6s per Instance. Within the limit increase screens I cannot find any option.

Does anyone know how to do this and if this is even possible?

Best Regards
Chris

Hello,

IP addresses are per network interface per instance type and cannot be changed. Therefore, if you require more IPv6 addresses, consider moving to a different Instance type. The following document lists the maximum number of network interfaces per instance type, and the maximum number of private IPv4 addresses and IPv6 addresses per network interface:
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html#AvailableIpPerENI

More information regarding changing instance types can be found in the below documentation:

Thank you for letting me know.

So I get a prefix with millions of addresses, but can use 2...
If you look at the link (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html#AvailableIpPerENI), it seems the IPv4 was just copied over to IPv6. Booking a different instance type would mean to get the largest available for just 50 IPv6. So basically rent the 747 to transport a peanut...

If you have any internal channels to give product improvements, please put in a hint, that IPv6 works different than IPv4. Hence the current limits are quite ridiculous (Especially as you get a /56 prefix assigned) and just produce IPv6 NAT and frustration with customers.
