Access list without wildcard mask

Hello dear friends .

It's my second question on Cisco forum. 

I would like to know when we write some standard access list without wild card mask which range of ip addresses will be proceed?

for example take a look at this one:

access-list 3 deny 10.17.32.0

so which range of ip addresses will be proceed ?

or this one 

access-list 2 permit host 172.16.14.0

Thanks for your response

Hi,This is the optional

Hi,
This is the optional option which you have in the standard acl.

Regarding your question, you are using the subnet  ( not a host) you will need to use the wildcard. The wildcard is optional because you can use instead the keyword hos ( 1 ip address) t or the keywork any ( any ip address) - See more at: https://supportforums.cisco.com/discussion/11369866/standard-acl-wildcard-mask-optional#sthash.WsgehniU.dpuf

eg:-

access-list 1 permit 192.168.1.1

It is identical to:
access-list 1 permit 192.168.1.1 0.0.0.0
That is the access list identifies an individual source address.

HTH
