Then what is the situation for firewalls already deployed and working in production? Most professional devices seem already to support IPv6. And the manufacturers of home equipment will tell you to buy a new device. (Unfortunately, equipment not supporting IPv6 is still sold!) And can we NAT IPv6 public IP with IPv4 private IP ranges? There is one major ...

I came to know recently ipv4 public ip address pools are going to exhausted soon. Depending on your definition of "exhausted" they already are. It's not like you can't get IPv4 though, just that the price is going up. Realistically what will happen is that as prices rise companies will reevaluate where they are using their IPv4. Connections that ...

NAT between IP4 and IP6 is pointless. NAT always changes only destination address (as in destination-NAT) or source address (as in source-NAT or masquerading). You will end up with a connection between an IP4 and an IP6 address. Neither of them supports such connection. Well, you can do both (SNAT + DNAT) in a single host and even encode IP4 addresses in an ...

And can we NAT IPv6 public ip with ipv4 private ip ranges. Since IPv6 addresses are abundant and allocated as /56 even for private access, there's absolutely no need for NAT (which is a kludge to deal with IPv4 public address scarcity). NAT64 for IPv6 was defined but there's little support - and that's a good thing.

You're late to the game: IPv4 addresses are already exhausted, and have been for a number of years. All the major manufacturers have included IPv6 capability (in varying degrees) in their product for quite some time.

Preferably, you configure the laser to use an address that fits your network. If that isn't possible to configure directly, it should be via DHCP - check the device's manual. If the address (and even more importantly the default gateway) cannot be configured, the devices TCP/IP implementation can be considered broken. As a workaround: Most PC operating ...

No. You can’t infer the subnet from the IP address alone.

Generally this network address 192.168.1.0/24 has total 254 usable hosts that means network 192.169.1.0/24 is representing total 254 hosts if any another networks want to communicate to this 254 host . Route entry is configured with as destination as 192.168 .1.0 so traffic will route to all 254 hosts if not we have to write 254 route entries which make ...

From IPv4 Multicast Address Space Registry Extensions for IP Multicasting [RFC1112] specifies the extensions required of a host implementation of the Internet Protocol (IP) to support multicasting. The multicast addresses are in the range 224.0.0.0 through 239.255.255.255. Address assignments are listed below. The range of addresses between 224.0.0.0 and ...

The address resolution protocol (arp) is a protocol used by the Internet Protocol (IP) [RFC826], specifically IPv4, to map IP network addresses to the physical addresses of host operates at layer 2 of OSI model . The protocol operates below the network layer as a part of the interface between the OSI network and OSI link layer. It is used when IPv4 is used ...

Yes, a switch is exactly what you need. Using a switch, each device can communicate with any other in the same network. The switch uses the interfaces' MAC addresses to direct the traffic where it should go - no further configuration required (only for TCP/IP, see below). It's like connecting them directly, the only difference is that without a dedicated ...

There aren't any special options to libpcap to understand the address because it's very unlikely that it's a valid one. However if you use netstat -tW so that you don't truncate the address in the first place, you will probably have more success.
