By default, When you give the Manual IP address in the Centos and after every restart it will deactivate the network interface and you have to activate the network connection manually after every reboot of the system. The reason it happens is that you have not configured the onboot system. Now let’s see, How you can do that… Read More »
In Mikrotik we can create the null route for IPv4 and IPv6 as well, just add a route like this: IPv4 Null Route Creation Example. /int bridge add name=Null0/ip add =10.10.10.1/24 int=Null0/ip route add dst=192.168.1.0/24 type=blackhole IPv6 Null Routing Creation Example. For IPv6 all are same but you have to use type=unreachable to configure the blackhole this effect… Read More »
I was troubleshooting an enterprise network for slowness the speed. So when I went through the troubleshooting steps I found that there is an IPv6 and IPv4 unknown unicast flooding that occurs in the Lan interface. it’s a medium enterprise where they have almost 400 end hosts including telephone and IP cameras as well. find the picture given… Read More »
In IPv4, the subnet mask 255.255.255.0 is 32 bits and consists of four 8-bit octets. The address: 10.10.10.0 subnet mask 255.255.255.0 means that the subnet is a range of IP addresses from 10.10.10.0 – 10.10.10.255. The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4. However, rather than being expressed in four octets like it is in IPv4, it is expressed as… Read More »
An IPv6 address consists of 32 hexadecimal digits, in 8 sections of 4 digits each, separated by colons. It looks something like this: 1234:5678:90ab:cdef:1234:5678:90ab:cdef IPv6 addresses have several shortcuts that allow them to be compressed into smaller strings following certain rules. If there are any leading zeroes in a section, they may be left off. 0001:0001:0001:0001:0001:0001:0001:0001 could be written as 1:1:1:1:1:1:1:1. Any… Read More »
In this blog, we will see the subnet size of IPv6, and also we will see some of the other information about IPv6 in this lesson. Let’s go ahead. IPv6 requires an IPv6-enabled network. IPv6 connectivity delivered directly by an ISP is ideal. Some ISPs deploy a dual stack configuration in which IPv4 and IPv6 are delivered simultaneously… Read More »
