Hi,
I have postgres version 12 running on centos 7.
I found an entry in my pg_hba.conf entry as given below under IPV4 connections:
host all all <remote_ip>/0 md5
I could not understand the meaning of "/0" here.
as I know that each IPV4 there are total 4 octets and each octet will be read based on given CIDR mask (/8, /16, /24 or /32) but I am watching first time "/0" that I couldn't understand, So please help me in explaining its prompt meaning and how IP will be read with /0?
Regards,
Atul
