我想使用Python和正则表达式从Cisco配置中提取网络组。该组以object-group network Cloudflare开头，紧接着是一个或多个类似network-object 173.245.48.0 255.255.240.0的子网。文本如下所示

object-group network Cloudflare
 network-object 173.245.48.0 255.255.240.0
 network-object 103.21.244.0 255.255.252.0
 network-object 103.22.200.0 255.255.252.0
 network-object 103.31.4.0 255.255.252.0
 network-object 141.101.64.0 255.255.192.0
 network-object 108.162.192.0 255.255.192.0
 network-object 190.93.240.0 255.255.240.0
 network-object 188.114.96.0 255.255.240.0
 network-object 197.234.240.0 255.255.252.0
 network-object 198.41.128.0 255.255.128.0
 network-object 162.158.0.0 255.254.0.0
 network-object 104.16.0.0 255.248.0.0
 network-object 104.24.0.0 255.252.0.0
 network-object 172.64.0.0 255.248.0.0
 network-object 131.0.72.0 255.255.252.0

当使用这个正则表达式(?P<name>object-group network Cloudflare)\n(?P<subnets> network-object \d+\.\d+\.\d+\.\d+ \d+\.\d+\.\d+\.\d+\n)*时，我得到了3个匹配组，其中只有第一个是可用的，但它包含头部object-group ...。可以改进吗？https://regex101.com/r/s925cq/1
