Dear Vinny,

Thanks for your valuable replay.

but I need a select query, which select only that record which starts from IP "172.23.110" only from below table.

xxx     172.23.110.175
yyy     172.23.110.178
zzz     172.23.110.177
aaa     172.23.110.176
bbb     172.23.111.180
ccc     172.23.115.26

 

​SELECT ... WHERE substring(ip_addr::text, 1, 10) = '172.23.110'

 

or

   select ... where ip_addr << '172.23.110/32';

 

if ip_addr is an inet data type -- https://www.postgresql.org/docs/9.6/static/functions-net.html
