DNS separation and resolution
DNS separation resolution is based on visitors from different regions, resolving the same domain name to get different addresses.
An experimental environment
a windows 10 pc as the host in the local area network
A windows 10 pc as an extranet host
A Linux PC as gateway
Two experimental topological graphs
Three experimental steps
1 After installing bind service program in Linux system, add a NIC, change the mode to host-only mode, configure gateway, ens33 NIC as local area network gateway, ens36 NIC as WAN gateway
2 change two pcs to host-only mode, configure ip, gateway address
3 Configure dns master profile, zone profile, zone data profile
4 Start services, turn off firewalls, enhance security features, resolve domain names
