Access list without wildcard mask

[mh.gorjizadeh]

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 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
