大部分用户只有直连区域, 因此无需强制填写.
对于无云区域的IP, 自动补齐云区域前缀 0:.

带云区域IP的正则表达式:

([0-9]+:)?(1?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])([.](1?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])){3}

测试:

s='1.1.1.1
0.0.0.0
1:1.1.1.1
255.255.255.255
256.1.1.1
00.1.1.1
::1
'
patt="([0-9]+:)?(1?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])([.](1?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])){3}"

echo "$s" | grep -wEo "$patt"
1.1.1.1
0.0.0.0
1:1.1.1.1
255.255.255.255
00.1.1.1
