Follow up to this Q&A.
Documentation regarding IP Access Lists is read to understand how this works and include or exclude it as a possible cause that some systems were suddenly not able to access the internet anymore.
If the access list would look like as follows:
access-list acl_permit permit ip 10.10.10.0 0.0.0.7 access-list acl_deny deny ip any any
this would mean that:
10.10.10.0 10.10.10.1 10.10.10.2 10.10.10.3 10.10.10.4 10.10.10.5 10.10.10.6 10.10.10.7
are able to access the internet, as:
2^0=1 2^1=2 2^2=4 + 7
If the access-list does not change and subsequently four more systems are created and the following IPs are assigned:
10.10.10.8 10.10.10.9 10.10.10.10 10.10.10.11
does this mean that these systems would not be able to access the internet?
Could it be possible that the new systems, e.g.
10.10.10.10 could compete with e.g.
10.10.10.4 so that the latter cannot access the internet anymore and the first does?
Or should the mask be increased from
7 to at least
15 so that the new systems (
10.10.10.8 - 11) could access the internet?
