Azure Virtual Networking – 10 how to manage ip address in network
IPAM (IP Address Management) is the administration of DNS and DHCP, which are the network services that assign and resolve IP addresses to machines in a TCP/IP network. Simply put, IPAM is a means of planning, tracking, and managing the Internet Protocol address space used in a network.
Public IP addresses allow Internet resources to communicate inbound to Azure resources. Public IP addresses enable Azure resources to communicate to Internet and public-facing Azure services. The address is dedicated to the resource, until it’s unassigned by you. A resource without a public IP assigned can communicate outbound. Azure dynamically assigns an available IP address that isn’t dedicated to the resource. For more information about outbound connections in Azure, see Understand outbound connections.
In Azure Resource Manager, a public IP address is a resource that has its own properties. Some of the resources you can associate a public IP address resource with:
Virtual machine network interfaces
Internet-facing load balancers
Virtual Network gateways (VPN/ER)
NAT gateways
Application gateways
Azure Firewall
Bastion Host
Standard
Standard SKU public IP addresses:
Always use static allocation method.
Have an adjustable inbound originated flow idle timeout of 4-30 minutes, with a default of 4 minutes, and fixed outbound originated flow idle timeout of 4 minutes.
Secure by default and closed to inbound traffic. Allowlist inbound traffic with a network security group.
Assigned to network interfaces, standard public load balancers, or Application Gateways. For more information about Azure load balancer, see Azure Standard Load Balancer.
Can be zone-redundant, which is advertised from all three zones. Zonal, which is guaranteed in a specific pre-selected availability zone. No-zone, which isn’t associated with a specific pre-selected availability zone. To learn more about availability zones, see Availability zones overview and Standard Load Balancer and Availability Zones. Zone redundant IPs can only be created in regions where three availability zones are live. IPs created before zones are live won’t be zone redundant.
Can be utilized with the routing preference to enable more granular control of how traffic is routed between Azure and the Internet.
Can be used as anycast frontend IPs for cross-region load balancers (preview functionality).
