[:: 1]在Django的ALLOWED_HOSTS中是什么意思？

Question

I was going through the documentation for Django's ALLOWED_HOSTS here

I came across a string ['localhost', '127.0.0.1', '[::1]'] in the ALLOWED_HOSTS .

Everything looks fine except the '[::1]' part.

I can't find a realtime scenario where '[::1]' is used.

Can someone please explain in which use case we will use this [::1]

Answer 1

[:: 1]是ipv6中的回送地址，等效于ipv4中的127.0.0.1。

Answer 2

我知道:: 1通常用于IPv6作为本地主机

Answer 3

That's most important part of settings - change ALLOWED HOSTS when you install your project to server. The settings there must be the same as in server configuration (eg nginx/gunicorn), but different for debug stage on local machine.

Advice: put all crucial settings like ALLOWED HOSTS in another one file in terms of security.

But while you're debugging-developing on local machine - you don't really need to change ALLOWED HOSTS .
