When i requested to 'localhost' host, the Postman sends SYN to IPv6, and then connects to IPv4. #10221
Comments
Closing due to age and inactivity. If this is still an issue you're facing in the latest version of the platform, we can look at reopening this again. |
The reason this happens is because localhost exists in both ipv6 (as ::1) and ipv4 (as 127.0.0.1). It checks first to see if an ipv6 connection is available as RFC 3484 states |
@montdidier OMG! Thank you for your comment. |
Is there an existing issue for this?
Describe the Issue
When I send a requested to 'localhost' host, it attempts to connect without having a Request Header in IPv6 (probably SYN).
Why is it working like this? Isn't it common to send either IPv4 or IPv6 requests?
If [::1] is a host, it is normal (including request headers).
If 127.0.0.1 is a host, it is normal (including request headers).
