想问一个IP段合并的问题

njblue2004

比如我找到的IP是这样的：
61.128.0.0/18
61.128.64.0/19
61.128.128.0/17
61.129.0.0/16
61.130.0.0/16
61.131.0.0/17
61.132.0.0/17
61.132.128.0/17
61.133.128.0/17
61.134.0.0/18
61.134.64.0/19
61.136.128.0/17
61.137.0.0/17
61.138.192.0/18
61.139.0.0/17
61.139.192.0/17
61.147.0.0/16
61.150.0.0/15
61.152.0.0/14
61.157.0.0/16
61.159.128.0/17
61.159.64.0/18
61.160.0.0/16
61.161.64.0/18
61.164.0.0/15
61.166.0.0/16
61.169.0.0/16
61.170.0.0/15
61.172.0.0/14
61.177.0.0/16
61.178.0.0/16
61.180.0.0/17
61.183.0.0/16
61.184.0.0/14

能用shell将这些IP段进行合并吗，这样在写到bind里面去的时候可以少写很多啊
（注：这只是一部分IP）

谢谢
