这是我在充分理解脚本后提出的几点修改建议 #5
Description
1.TARGET_IP变量在调用系统命令ifconfig时可以加入| grep 'inet6 (ipv6固定前缀)'来避免某些情况下公网ipv6地址行数跳变的情况，ipv6固定前缀可以只输入头4位如2049即可
2.建议加入对云解析地址与本机ipv6地址的比较判断，不同时则调用api修改，相同时则不做修改，以下是我魔改后获取云解析地址的代码
HWcloud_IP=$(echo $(curl -X GET -L -k "https://$DNS/v2/zones/$ZONE_ID/recordsets/$RECORDSET_ID" \ -H "X-Auth-Token: $TOKEN" \ -H "Content-Type: application/json" \ -H "X-Project-Id: $PROJECT_ID")| sed 's/,/\n/g'|grep 'records'| grep -oE '(([0-9a-fA-F]{1,4}:){7,7}[0-9a-fA-F]{1,4}|([0-9a-fA-F]{1,4}:){1,7}:|([0-9a-fA-F]{1,4}:){1,6}:[0-9a-fA-F]{1,4}|([0-9a-fA-F]{1,4}:){1,5}(:[0-9a-fA-F]{1,4}){1,2}|([0-9a-fA-F]{1,4}:){1,4}(:[0-9a-fA-F]{1,4}){1,3}|([0-9a-fA-F]{1,4}:){1,3}(:[0-9a-fA-F]{1,4}){1,4}|([0-9a-fA-F]{1,4}:){1,2}(:[0-9a-fA-F]{1,4}){1,5}|[0-9a-fA-F]{1,4}:((:[0-9a-fA-F]{1,4}){1,6})|:((:[0-9a-fA-F]{1,4}){1,7}|:)|fe80:(:[0-9a-fA-F]{0,4}){0,4}%[0-9a-zA-Z]{1,}|::(ffff(:0{1,4}){0,1}:){0,1}((25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])\.){3,3}(25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])|([0-9a-fA-F]{1,4}:){1,4}:((25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])\.){3,3}(25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9]))')
