Datadog Log Management offers an intuitive syntax for CIDR queries, allowing users to search for logs within a subnet by filtering on its corresponding CIDR block. This enables network engineers and analysts to efficiently allocate IPs in virtual private clouds (VPCs) and other networks. By using CIDR notation, users can identify traffic from unexpected sources, analyze network performance, and spot failures. The syntax also makes it easy to create supernetting within a VPC, improving network traffic efficiency by allowing request data to reach the destination address without taking unnecessary paths.
