Experts,

We are considering implementing Private VLANs in order to save public IPv4
space and I am hoping to get feedback from those that have deployed and/or
tested it.

Our main drivers for implementing it is to mitigate the following scenarios:

   - Placing Subnet A's servers into Subnet B's vlan due to IP space
   limitations
   - Unused IP space in VLANs that waste 30-49% of IP space
   - Placing secondary IP addresses onto external VLANs due to growth
   requirements
   - Tedious work in re-sizing subnets due to over-allocating IPs and need
   to re-purpose
   - Scrambling to get temporary IP space for product launches from service
   providers in multiple regions

Given this use-case, would you recommend the technology (private-vlan) or
not?

Best Regards,

Kristian J. Francisco
