Does the core switch have DNC functionality

Core switches do not inherently provide DNC (domain name control) functionality; they primarily handle high-speed data switching, routing, and can configure DNS servers for resolution purposes.Core Switch CapabilitiesCore switches are high-performance network devices positioned at the backbone of a network. Their primary functions include:High-speed data switching and routing between subnets, VLANs, and network segments .Traffic aggregation and forwarding with low latency to ensure network reliability and performance .Support for routing protocols like OSPF and BGP, VLAN segmentation, and redundancy features .Security features such as ACLs, port security, and integration with firewalls or intrusion detection systems .Management and monitoring via SNMP, CLI, and modular designs for scalability .DNS and Domain ControlWhile core switches can be configured with DNS server settings to resolve domain names for network devices, they do not perform DNC functions such as domain blocking, filtering, or advanced domain-level control. Any domain-based access control or filtering is typically handled by:Client-side applications or browser add-onsDedicated security appliances like firewalls or DNS filtering services Configuring a core switch to use a specific DNS server (e.g., ISP DNS or Google Public DNS) only affects how the switch resolves domain names for its own management or network services; it does not enforce domain-level policies across the network .ConclusionCore switches are designed for high-speed backbone switching, routing, and network management, not for DNC functionality. For domain-level control, organizations should deploy dedicated DNS filtering solutions or security appliances in conjunction with the core switch.
