✑ 192.168.15.10
✑ 192.168.15.11

Differences Between the HOSTSand LMHOSTS Files in Windows NT
In Windows NT, the HOSTS file is for TCP/IP utilities, and the LMHOSTS file is for LAN Manager NET utilities. If you cannot PING another computer (using a friendly name), check the HOSTS file. If you cannot NET VIEW a server using only the TCP/IP protocol, check the LMHOSTS file.
The Hosts file is a common way to resolve a host name to an IP address through a locally stored text file that contains IP-address-to-host-name mappings. On most UNIX-based computers, this file is/etc/hosts. On Windows-based computers, this file is the Hosts file in the systemroot\System32\Drivers\Etc folder. The following describes the attributes of the Hosts file for Windows: A single entry consists of an IP (IPv4 or IPv6) address and one or more host names. The Hosts file is dynamically loaded into the DNS client resolver cache, which Windows Sockets applications use to resolve a host name to an IP address on both local and remote subnets. When you create entries in the Hosts file and save it, its contents are automatically loaded into the DNS client resolver cache. The Hosts file contains a default entry for the host name localhost. The Hosts file can be edited with any text editor. Each host name is limited to 255 characters. Entries in the
Hosts file for Windowsbased computers are not case sensitive. The advantage of using a Hosts file is that users can customize it for themselves. Each user can create whatever entries they want, including easy-to-remember nicknames for frequently accessed resources. However, the individual maintenance required for the Hosts file does not scale well to storing large numbers of FQDN mappings or reflecting changes to IP addresses for servers and network resources. The solution for the large-scale storage and maintenance of FQDN mappings is DNS. The solution for the maintenance of FQDN mappings for changing IP addresses is DNS dynamic update.
