Geo
Description: Provides quick access for wan, lan, router, dns, mac, and ip geolocation data
Usage: geo [flag]
-w Returns WAN IP
-l Returns LAN IP(s)
-r Returns Router IP
-d Returns DNS Nameserver
-m Returns MAC address for interface. Ex. eth0
-g Returns Current IP Geodata
Examples:
geo -g
geo -wlrdgm eth0
Custom Geo Output => [all] [query] [city] [region] [country] [zip] [isp]
Example: geo -a 8.8.8.8 -o city,zip,isp
-o [options] Returns Specific Geodata
-a [address] For specific IP in -s
-v Returns Version
-h Returns Help Screen
-u Updates Bash-Snippets
