Dual stack instance cannot talk to IPv6 sites but works with IPv4 sites

Simon MandyNov 17 2024

Hello,

I have created a cloud instance with IPv6 and IPv4 address.

xxxx@xxx:~$ ifconfig | grep inet6
inet6 2603:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx prefixlen 128 scopeid 0x0<global>
inet6 fe80::xxxx:xxxx:xxxx prefixlen 64 scopeid 0x20<link>
inet6 ::1 prefixlen 128 scopeid 0x10<host>

From the instance I do, curl -I google.com it works(I get 301 response). But if I do curl -6 -I google.com it get stuck.

The instance is created under a vcn with IPv6 enabled. IPv6 prefix shows on the vcn shows 2603:xxxx:xxxx:xxxx::/56 and subnet IPv6 prefixes shows 2603:xxxx:xxxx:xxxx:0000:0000:0000:0000/64 CIDR Blocks/Prefixes has 2603:xxxx:xxxx:xxxx::/56

The Default Route Table got Rule for,

Destination - ::/0

Target Type - Internet Gateway

Target - My Default Internet Gateway

I got two Security Lists, default and custom I created, In custom one I added below rules,

Egress -

Rule1 -

Destination - 0.0.0.0/0

IP Protocol - All Protocols

Rule2 -

Destination - ::/0

IP Protocol - All Protocols

Any thoughts?

How doc gen treats nulls values?

You have to be more specific. Are your referring to the pre-built Document Generator function?

If so:

When my query return null in some columns

What is the JSON that is generated?

You should always include the element in the JSON, with an empty value. Don't leave it out.

Since September 2024, when a tag has no corresponding value in the JSON data or the value is null, the tag is replaced by an empty string.
