getip

Name

getip - get external IP from akamai and google (HTTP and DNS)

Synopsis

getip

Description

getip uses two methods to retrieve the external IP address of the box:

• "whatismyip.akamai.com" over HTTPS. For the HTTPS download either curl, wget, perl or python is used.
• query one of Googles nameservers that returns your external IP. For the query dig or host is used.

Google and Akamai were chosen as they are less suspect than, say, ifconfig.co or whatever in any upstream logs.

Command Source Code

getip() {
#we use akamai and google here because they're gonna look less dodgy in SOC's lolgs
echo "Attempting to get IP..."
echo -ne "HTTP says: "
	orc_loadURL 'https://whatismyip.akamai.com'
echo ""
echo -ne "DNS says: "
	if hash dig>/dev/null; then
	dig TXT +short o-o.myaddr.l.google.com @ns1.google.com | tr -d \"
	echo -ne "(used dig)\n"
	else
	host -t txt o-o.myaddr.l.google.com ns1.google.com | grep descriptive | awk -F ' ' '{print $4}' | tr -d '"' | tr -d "\n"
	echo -ne "(used host)\n"
	fi
