Hosts /

Host and network name database

Note: The /etc/hosts file may be consulted before any name servers. Avoid hard-coding any values that may change. It is best to rely on nameservers.

/etc/hosts

As stated in the OpenBSD manual, the hosts file associates names and IP addresses. The file format is quite simple. Each line holds this format:

Internet address IPV4/IPV6	Host name	Aliases
100.10.20.31	PEPPINO	PEPPINO.oddprotocol.org

Every line field is separated using one or more spaces or one or more tabs character. a '#' character indicates a comment. The comment starts from this character to the end of the line. Every character in this space is ignored. To edit /etc/hosts just use:

$ doas vi /etc/hosts
