router access list question

[niqsterd]

Hi,
In a cisco router.
Is there any difference between having ten entries in access list number 1 and having 1 entry each in access lists 1 through 10?

for instance if I want to block traffic to 10 different ip addresses (web sites). Is one method perfered? easier? am I misunderstanding something with access lists?

Why do I see some access lists with the only entry being in an access list other # than 1?. Why not start at #1?

thanks

No you don't make 10 different lists you make one and then apply that access list to whatever interface you want to control traffic over .

the 1 references a group or container
for example access-list 1 permit 10.0.0.1
access-list 1 deny any

above are two rules for access-list (rule set 1)

you then apply this to an interface by using the ip access-gr 1 in or out depending on inbound or outbound traffic
