But almost all leading operating systems use the name 'localhost' to represent an IPv4 loopback address 127.0.0.1. In IPv4, we have an entire network (127.0.0.0/8) reserved as loopback addresses. The loopback addresses are typically used by programmers for development and testing of network applications without even having network configurations. Whenever we communicate to a loopback address (both in IPv4 and IPv6) the TCP/IP protocol stack will loop the packets back on the same interface, without even leaving the interface.

GATE CS Original Papers and Official Keys By default, the 6to4 tunneling protocol is enabled in Windows when an interface is assigned a public IPv4 address (Public IPv4 address means any IPv4 address that isn't in the ranges 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16).The loopback addresses (both in IPv4 and IPv6) is an address which represents the same interface of a computer. Like IPv4, provision has been made for a special loopback address for testing datagrams sent to this address loop back to the sending device. ISRO CS Original Papers and Official Keys.Ħto4 automatically assigns an IPv6 address to the 6to4 tunneling interface for each address, and 6to4 dynamically registers these IPv6 addresses on the assigned DNS.ISRO CS Syllabus for Scientist/Engineer Exam.Preparation Tips for Quantitative Ability (QA) Section in CAT.Vocabulary for CAT and Aptitude Related Exams | Set 2.Finding cabs nearby using Great Circle Distance formula.

Program to remotely Power On a PC over the internet using the Wake-on-LAN protocol.Network Devices (Hub, Repeater, Bridge, Switch, Router, Gateways and Brouter).Domain Name System (DNS) in Application Layer.Internet Protocol version 6 (IPv6) Header.Internet Control Message Protocol (ICMP). Local Broadcast Address is used to communicate with all the devices on a local network.

It is represented by 255.255.255.255 or 11111111.11111111.11111111.11111111 in binary.Ī broadcast address is used by hosts to request IP addresses from the DHCP(Dynamic Host Configuration Protocol) server. The host sends a broadcast to the broadcast address to request an IP address and in turn the DHCP server allocates an IP address from the pool of IP addresses.īy default, local broadcast address is always dropped by routers and layer 3 switches but one can always override this by configuring the device with DHCP forwarding or DHCP relay. I am using Apache webserver 2.2.11.At present i am able to browse my website using IPv4 loopback address.Instead of this IPv4 loopback address (127.0.0.1) i need to use IPv6 loopback address (::1) to browse the website.I have already tried to add this address in nfig. Local Loopback Address is used to let a system send a message to itself to make sure that TCP/IP stack is installed correctly on the machine. But apache server didn't start after this change due. In IPv4, IP addresses that start with decimal 127 or that has 01111111 in the first octet are loopback addresses(127.X.X.X). Typically 127.0.0.1 is used as the local loopback address. This leads to the wastage of many potential IP addresses. But in IPv6 ::1 is used as local loopback address and therefore there isn’t any wastage of addresses.
