Checking Local IP is UP (or) DOWN

Checking Local IP is UP (or) DOWN :
An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: “A name indicates what we seek. An address indicates where it is. A route indicates how to get there.”

Checking Local IP Automated Script :
for ((n=0 ; n < 30 ; n+=1))
if ping -c 1 -w 1 $ip > /dev/null 2> /dev/null >> /etc/logping.txt; then
echo “${ip} is up”
echo “${ip} is down”
is_alive_ping $i & disown

Output Details :
Output –> It will display like “Local Network is Up” is down is up is up is up is down is up is down is down is down is down is down is down is down is down is down

NOTE –> I Just Specified “Local IP-Address” But Actually Your Local IP Address will be Display there.

Local IP-Address will Display :

IP=”$(ifconfig | egrep ‘inet ‘ | sed -e ‘s/inet //’ -e ‘s/addr://’ -e ‘s/ Bcast.//’ -e ‘s/127.//’)”
echo $IP

Output Details :
It Will Display Local IP-Address

Output –> Local IP Address

IPv6 Disabling

What is IPV6 :
Internet Protocol Version 6 (IPv6) is a network layer protocol that enables data communications over a packet switched network. Packet switching involves the sending and receiving of data in packets between two nodes in a network. The working standard for the IPv6 protocol was published by the Internet Engineering Task Force (IETF) in 1998. The IETF specification for IPv6 is RFC 2460. IPv6 was intended to replace the widely used Internet Protocol Version 4 (IPv4) that is considered the backbone of the modern Internet. IPv6 is often referred to as the “next generation Internet” because of it’s expanded capabilities and it’s growth through recent large scale deployments. In 2004, Japan and Korea were acknowledged as having the first public deployments of IPv6.

IPv6 is the next generation Internet Protocol (IP) address standard intended to supplement and eventually replace IPv4, the protocol most Internet services use today. Every computer, mobile phone and any other device connected to the Internet needs a numerical IP address in order to communicate with other devices.  The original IP address scheme, called IPv4, is running out of numbers.  Please see the Internet Society IPv6 Fact Sheet or  our IPv6 Basics page for more information and background on IPv6.  Our list of IPv6 statistics sites can also show you the most recent trends in growth of IPv6 usage.

IPv6 Features :
1) New header format

2) Large address space

3) Efficient and hierarchical addressing and routing infrastructure

4) Stateless and stateful address configuration

5) Built-in security

6) Better support for quality of service (QoS)

7) New protocol for neighboring node interaction

8) Extensibility

IPv6 Disabling Script :

int=$(netstat -i | cut -d” ” -f1 | egrep -v “^Kernel|Iface|lo|:” |head -1)

ip -6 addr show dev $int |cut -b 5-9 >/tmp/ipp

grep “inet6” /tmp/ipp >/dev/null 2>&1 && ip_v=1 || ip_v=0

i6=$(ip addr show dev $int | sed -e’s/^.inet6 ([^ ])\/.*$/\1/;t;d’)
if [ $ip_v -eq 1 ]

echo “echo IPv6 found…”;
echo “The IPv6 address is $i6”;
echo “Disabling IPv6 address…”;
echo “net.ipv6.conf.all.disable_ipv6 = 1” >> /etc/sysctl.conf
echo “net.ipv6.conf.default.disable_ipv6 = 1” >> /etc/sysctl.conf
echo “net.ipv6.conf.lo.disable_ipv6 = 1” >> /etc/sysctl.conf
sysctl -p
echo “IPv6 address disabled”
echo “IPv6 is already disabled”


rm -f /tmp/ipp
