可以通过curl或者http请求
一共有30条命令，最下面有简要说明

curl ipv4.dreamdusk.com
curl ipv4.dreamdusk.com/me
curl ipv4.dreamdusk.com/ip/1.1.1.1

curl https://ipv4.dreamdusk.com
curl https://ipv4.dreamdusk.com/me
curl https://ipv4.dreamdusk.com/ip/1.1.1.1

curl ipv6.dreamdusk.com
curl ipv6.dreamdusk.com/me
curl ipv6.dreamdusk.com/ip/1.1.1.1

curl https://ipv6.dreamdusk.com
curl https://ipv6.dreamdusk.com/me
curl https://ipv6.dreamdusk.com/ip/1.1.1.1

curl ip.dreamdusk.com
curl ip.dreamdusk.com/me
curl ip.dreamdusk.com/ip/1.1.1.1

curl https://ip.dreamdusk.com
curl https://ip.dreamdusk.com/me
curl https://ip.dreamdusk.com/ip/1.1.1.1

curl 4.dreamdusk.com
curl 4.dreamdusk.com/me
curl 4.dreamdusk.com/ip/1.1.1.1

curl https://4.dreamdusk.com
curl https://4.dreamdusk.com/me
curl https://4.dreamdusk.com/ip/1.1.1.1

curl 6.dreamdusk.com
curl 6.dreamdusk.com/me
curl 6.dreamdusk.com/ip/1.1.1.1

curl https://6.dreamdusk.com
curl https://6.dreamdusk.com/me
curl https://6.dreamdusk.com/ip/1.1.1.1

一、总目标就是：

4或6开头的，直接获取ip

ipv4或ipv6开头的，获取当前ip的信息

短的(4或6)开头获取到短的ip

长的(ipv4或ipv6)开头获取到长的信息

二、/me，和总目标相反

4.dreamdusk.com/me或者6.dreamdusk.com/me，获取当前ip的信息

ipv4.dreamdusk.com/me或者ipv6.dreamdusk.com/me，直接获取ip

短的开头+/me获取到长的信息

长的开头+/me获取到短的ip

三、特殊，ip开头

ip.dreamdusk.com套了cdn，获取到ipv4还是ipv6说不定，会返回连接到cdn的ip

ip.dreamdusk.com/me，返回连接到cdn的ip的信息

部分版本的curl可以用-4或者-6指定使用ipv4还是ipv6访问

如curl -4 ip.dreamdusk.com

四、前三种方式都可以用的

任意开头+/ip/x.x.x.x，获取ipx.x.x.x的详细信息(ipv4、ipv6均可)

也就是说

• 1

4.dreamdusk.com=ipv4.dreamdusk.com/me

6.dreamdusk.com=ipv6.dreamdusk.com/me

• 2

ipv4.dreamdusk.com=4.dreamdusk.com/me

ipv6.dreamdusk.com=6.dreamdusk.com/me

• 3

4.dreamdusk.com/ip/x.x.x.x

=6.dreamdusk.com/ip/x.x.x.x

=ipv4.dreamdusk.com/ip/x.x.x.x

=ipv6.dreamdusk.com/ip/x.x.x.x

=ip.dreamdusk.com/ip/x.x.x.x
