Edge networks
In zCompute, Edge Networks provide the connectivity between VPC entities (e.g VMs, load-balancers) and the Internet or any other local datacenter-routable network. Under an Edge Network one or more IP-address pools can be defined. These IP pools are then used to create Elastic-IPs, that when attached to a VM, allow traffic from outside the cloud (Internet or the hosting datacenter to reach the VM. A single zCompute region may have multiple Edge Networks, each with multiple IP pools. IP pools can be public, available for all tenant accounts, or private to specific accounts. Edge Networks use VLANs to connect the cloud region to the hosting datacenter’s upstream switches and L3 gateways.

Configuring a services proxy
There may be several reasons for configuring a services proxy, including:
To force managed-services traffic through a controlled egress path.
To use a proxy that requires authentication.
To let some destinations bypass the proxy, by defining an exclusion list
Use this action when managed services for the edge network must use a proxy.
Note
Keep the exclusion list focused.
A smaller bypass list is easier to review and support.
Review the Overview tab after saving proxy values.
The tab shows the stored HTTP proxy, HTTPS proxy, and exclusion list when proxy data exists.
Open the edge network details page.
Select Services Proxy.
The Configure Managed Services Proxy dialog opens.
Enter the fields:

Are you sure you want to delete this edge network?
The confirmation prompt warns that the selected edge network will be removed.
Use it as the final review step before deletion.
ID
The unique edge network ID shown in the prompt.
Use it to confirm the exact object to delete.
Name
The edge network name shown in the prompt.
Use it to confirm that the selected object is the correct one.
To delete the edge network, select Delete.
Recommended best practices for edge network management
Plan Switch Domain, VLAN ID, and Untagged values before you create the edge network.
The create/edit form allows these values at creation time, but the edit form disables Switch Domain, VLAN ID, and Untagged. That makes them design-time choices, not routine change-time values.
Use the default MTU unless you have a clear reason to change it, and keep MTU changes controlled.
The form always requires MTU and defaults it from the edge-network default. The input validation check also enforces minimum and maximum MTU values, which indicates that MTU is a core network setting that should be chosen carefully.
Treat subnet CIDR as stable after creation.
In the Subnet step, the CIDR field is disabled for editing once the subnet record already exists. That means you should choose the subnet range carefully before production use.
Validate Gateway carefully against the subnet.
The input validation checks the gateway IP against the subnet CIDR and excludes boundary addresses. A practical best practice is to review the subnet and gateway together before saving changes.
Enter only valid IP addresses in DNS Servers, and keep the list intentional.
The DNS Servers field accepts multiple values and validates them as IPs. That makes it a good place to keep only the resolvers that are actually required for that subnet.
Use the edge network state as your first pre-change check.
The UI enables Edit only when the edge network state is Available.
It disables Delete when the state is Pending.
Before any maintenance, verify that the network is in the right state.
Keep Public IP assignment deliberate.
If no public IP is provided in the Network step, a random available IP is allocated from the IP pool. Use an explicit value when you need predictable router addressing, and leave it empty only when automatic assignment is acceptable.
Use the Services Proxy only when managed services actually need a proxy path, and keep the bypass list tight.
The action stores proxy settings on the edge network, and the UI is specifically for managed-services proxy configuration. Because the Services Proxy dialog includes HTTP/HTTPS endpoints and an exclusion list, it is best to keep the configuration minimal and reviewable.
Review free address space before creating an IP pool.
The IP pool dialog fetches unused ranges for the edge network and only presents IP-range entry when there is an existing pool to modify or unused ranges to consume.
Check available space before adding more pools.
Use Shared IP pools only when that access model is intentional; otherwise assign accounts explicitly.
In the IP pool dialog, when Shared is not selected, Accounts becomes required. That implies a clear operational split between shared pools and account-scoped pools.
Do not plan routine changes to the routers IP pool.
The IP pool actions disable Modify and Delete for internal pools, with the message Routers IP Pool is managed internally. Treat router pools as platform-managed resources.
Use the built-in two-step workflow as your change checklist: Network first, then Subnets.
The dialog explicitly separates these into two steps. In practice, this is a good admin habit as well: review network-wide properties first, then validate subnet addressing.
Before deleting an edge network, confirm both identity and state.
The delete prompt shows the network ID and Name, and the UI disables delete while the network state is Pending. That means the safest delete workflow is: verify state, then verify exact identity in the confirmation prompt.
Troubleshooting
The edge network is not editable
Check the edge network state first.
The UI enables Edit only when the state is Available.
A field is visible but cannot be changed
This can be expected behavior.
Switch Domain, VLAN ID, and Untagged are disabled in edit mode. The subnet CIDR field is also disabled when the subnet record already exists.
A gateway value is rejected
Review the subnet CIDR first.
The system validates the gateway value against the subnet CIDR and excludes boundary addresses.
A DNS server value is rejected
Review the entered value format.
The system validates the DNS Servers field as IP values.
You are not sure whether a delete action is safe
On the edge network’s details page, review these tabs first:
Overview
Review the exact network, subnet, router, and routers subnet records.
IP Pools
Review current pool usage and ranges.
VPC Projects
Review dependent project usage.
Events
Review recent activity after the latest change.
