• GLOBAL Picks a global IP address if available. If not, falls back to a SITE_LOCAL IP address.
• SITE_LOCAL Picks a site local (non routable) IP address, e.g. from the 192.168.0.0 or 10.0.0.0 address range.
• LINK_LOCAL Picks a link-local IP address, from 169.254.1.0 through 169.254.254.255.
• NON_LOOPBACK Picks any non loopback address.
• LOOPBACK Pick a loopback address, e.g. 127.0.0.1.
• match-interface Pick an address which matches a pattern against the interface name, e.g. match-interface:eth.*
• match-address Pick an address which matches a pattern against the host address, e.g. match-address:192.168.*
• match-host Pick an address which matches a pattern against the host name, e.g. match-host:linux.*
