我正在尝试制作一个PHP脚本，该脚本生成并向eth0分配一个随机IPv6地址，并执行HTTP请求，但似乎所有地址都需要通过首先发出一个伪请求来"初始化"。但是，我需要IP在创建后的一秒钟内为HTTP请求做好准备。经过数小时的测试和互联网搜索，我找不出问题，所以我来到了这里。
我的Debian VPS有一个/64 IPv6地址空间分配给它。
为了解释这个问题，我这样做了：
首先，我手动分配9个IP
ip addr change 2001:19f0:xxxx:xxxx:xxxx:xxxx:2:1 dev eth0 valid_lft 600 preferred_lft 600
ip addr change 2001:19f0:xxxx:xxxx:xxxx:xxxx:2:2 dev eth0 valid_lft 600 preferred_lft 600
ip addr change 2001:19f0:xxxx:xxxx:xxxx:xxxx:2:3 dev eth0 valid_lft 600 preferred_lft 600
ip addr change 2001:19f0:xxxx:xxxx:xxxx:xxxx:2:4 dev eth0 valid_lft 600 preferred_lft 600
ip addr change 2001:19f0:xxxx:xxxx:xxxx:xxxx:2:5 dev eth0 valid_lft 600 preferred_lft 600
ip addr change 2001:19f0:xxxx:xxxx:xxxx:xxxx:2:6 dev eth0 valid_lft 600 preferred_lft 600
ip addr change 2001:19f0:xxxx:xxxx:xxxx:xxxx:2:7 dev eth0 valid_lft 600 preferred_lft 600
ip addr change 2001:19f0:xxxx:xxxx:xxxx:xxxx:2:8 dev eth0 valid_lft 600 preferred_lft 600
ip addr change 2001:19f0:xxxx:xxxx:xxxx:xxxx:2:9 dev eth0 valid_lft 600 preferred_lft 600
PHP脚本：
<?php
$URL = "ipv6.whatismyv6.com";
for($i=1; $i<10; $i++)
{
$ch = curl_init();
$IP = "2001:19f0:xxxx:xxxx:xxxx:xxxx:2:{$i}";
curl_setopt($ch, CURLOPT_URL, $URL);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLINFO_HEADER_OUT, TRUE);
// Set IPv6
curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V6);
curl_setopt($ch, CURLOPT_INTERFACE, $IP);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 60);
curl_setopt($ch, CURLOPT_TIMEOUT, 120);
print "IP {$IP}'n";
curl_exec($ch);
if(curl_errno($ch))
die(curl_error($ch));
var_dump(curl_getinfo($ch));
print "'nDone for IP {$IP}'n'n";
curl_close($ch);
}
在第一次运行脚本时，我得到了这个输出。正如您所看到的，除了第一个请求外，每个请求的connect_time都是32秒。看起来cURL在尝试连接之前需要花费30秒的时间。

此外，
wget --bind-address=2001:19f0:xxxx:xxxx:xxxx:xxxx:3:1 http://ipv6.whatismyv6.com
与PHP脚本中的第一个请求一样，工作得很好。
我已经和这个问题斗争了好几天了，所以我们非常感谢您的帮助。
添加IPv6地址后，系统通常会进行重复地址检测（DAD），以确保没有其他系统使用相同的地址。这可能需要几秒钟的时间。如果你真的需要能够立即使用地址，你需要在接口上禁用DAD:
echo 0 > /proc/sys/net/ipv6/conf/eth0/accept_dad
