postgis - Modifying "pg_hba.conf" file to listen local TCP/IP conection?

I am starting with PostGIS and there is an error when trying to connect through a TCP/IP connection. What I have done is: installed PostGre 9.3 in my PC, then installed PostGIS 2.3 for postGre 9.3, then I tested the database in my computer using localhost and all worked fine, then I wanted to connect to the database form another computer that is in the same network (from now on, PC2).. I read many forums and then modify pg_hba.conf trying to allow PC2 to connect. I just couldn´t.

Default file:

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
#host    replication     postgres        127.0.0.1/32            md5
#host    replication     postgres        ::1/128                 md5

And this is how I modified it:

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
host    all             all             10.0.0.99               md5
# IPv6 local connections:
host    all             all             ::1/128                 md5
# Allow replication connections from localhost, by a user with the

# replication privilege.
#host    replication     postgres        127.0.0.1/32            md5
#host    replication     postgres        ::1/128                 md5

note that the new value is 10.0.0.99, which is the IP address of PC2.

Can anyone help?

Was dealling with same problem just few hours ago.

I think you should add a CIDR mask length (/32 for a single address - Wikipedia details) in ip-address section:

# TYPE  DATABASE        USER            ADDRESS                 METHOD


# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
host    all             all             10.0.0.99/32               md5
.
.
.

After saving pg_hba.conf file you should restart server with new configuration just run pgAdmin and choose Reload configuration in Tools menu:
