Default address range on WordPress on Azure about wordpress-linux-appservice

[arjunbaliga]

Hello @bmanjwani - Thank you for investigating this. I believe we should retain 10.0.0.0/16 as the default address range for the VNET. If customers encounter issues with this address range, they can consider changing it to 10.0.0.0/24. Please provide your suggestions.

@arjunbaliga I would like to understand the issue customers are facing with regards to having a broader address range for VNET. Currently default VNET address range is 10.0.0.0/16. This range allows for a total of 65K IP addresses, providing a wide pool of addresses for the customer to utilize.
However, if we consider a narrower address range like 10.0.0.0/24, there will be 256 address spaces available for use. Out of these, 5 addresses will be reserved within each subnet, leaving them with only 123 usable IPs in each subnets (app and database).

@arjunbaliga I agree to this. By default, we will keep the address range for the virtual network (VNet) as 10.0.0.0/16. This provides a broader range of IP addresses for potential use. However, if a customer wants a lesser range, they can consider having a custom address range for the VNet or subnet. This gives them the flexibility to choose a specific address range that suits their requirements.

the issue about having a /16 network is that its almost impossible to peer the VNET with any existing infrastructure.
also nobody will create a wordpress environment that requires a /16 range, probably not even a /24 but at least a /24 is more compatible with other VNETs. In any case if the customers want to extend the /24 they can just create additional address ranges on the VNET, whereas its not impossible to reduce.

@arjunbaliga @pmmota We have added it to our backlog and will address it as soon as we can. I will keep you informed about the progress and deployment of this change request.

@arjunbaliga We have modified the default address range of vnet, change is deployed and available on production.
Current VNET range - /23
Db and App Subnet range - /25
