# CIDR-ADDRESS specifies the set of hosts the record matches.
# It is made up of an IP address and a CIDR mask that is an integer
# (between 0 and 32 (IPv4) or 128 (IPv6) inclusive) that specifies
# the number of significant bits in the mask.  Alternatively, you can
write
# an IP address and netmask in separate columns to specify the set of
hosts.
 
In other words, it says how many bits of the IP address need to match.
 
For example:
 
# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

# "local" is for Unix domain socket connections only
local   all         postgres                          ident sameuser
local   cir         all                               md5

# IPv4 local connections:
host    cir         all         127.0.0.1/32          md5
# IPv6 local connections:
host    cir         all         ::1/128               md5

# Programmer/analyst network segment
host    cir         all         165.219.88.0/22       md5
# STEP network segment
host    cir         all         165.219.80.0/24       md5
# TECH network segment
host    cir         all         165.219.95.0/24       md5
