The Ultimate Guide To Lmhosts: Configuration And Troubleshooting

rainbow8 29 Jun 2024

What is lmhosts?

Lmhosts is a text file used by the Windows operating system to map hostnames to IP addresses. It is similar to the DNS (Domain Name System), but it is stored locally on the computer. Lmhosts is used to resolve hostnames for computers that are not connected to a DNS server or for computers that need to have a local override for a hostname.

Lmhosts can be used to improve the performance of name resolution and to provide a backup in case the DNS server is unavailable. It can also be used to create aliases for hostnames, which can be useful for testing purposes or for creating a more user-friendly naming scheme.

Here is an example of an lmhosts file:

192.168.1.100 server1192.168.1.101 server2192.168.1.102 server3

In this example, the lmhosts file maps the hostname "server1" to the IP address "192.168.1.100", the hostname "server2" to the IP address "192.168.1.101", and the hostname "server3" to the IP address "192.168.1.102".

Lmhosts is a useful tool that can be used to improve the performance and reliability of name resolution on Windows computers.

Improved name resolution performance: Lmhosts can help to improve the performance of name resolution by caching the results of DNS lookups. This can be especially beneficial for computers that are not connected to a DNS server or for computers that need to have a local override for a hostname.
Backup for DNS: Lmhosts can provide a backup in case the DNS server is unavailable. This can help to ensure that computers can still resolve hostnames even if the DNS server is down.
Hostname aliases: Lmhosts can be used to create aliases for hostnames. This can be useful for testing purposes or for creating a more user-friendly naming scheme.

lmhosts

Lmhosts was first introduced in Windows NT 3.1. It was originally used to resolve NetBIOS names, but it was later extended to support DNS names as well. Lmhosts is still used in Windows 10, but it is no longer as important as it once was. This is because most computers are now connected to DNS servers, and lmhosts is not as necessary for improving name resolution performance.

However, lmhosts can still be useful for providing a backup in case the DNS server is unavailable or for creating hostname aliases. It is also sometimes used for troubleshooting DNS issues.
