Let begging about deference between IPv6 and IPv4. 1: Length IPv4: 32 Bit IPv6: 128 Bit 2: Number of header fields IPv4: 12 fields IPv6: 8 fields 3: Checksum IPv4: Has checksum fields IPv6: Does not have checksum fields 4: Examples IPv4: 1.1.1.1 150.50.0.1 192.168.10.1 224.0.0.5 127.0.0.1 IPv6: ::1 2001:0db8:0000:0000:0000:ff00:0042:7879 fec0:0:0:ffff::2 fe80::89b4:75f6:816:55ac 2001:4860:4860::8888 5: Type of Addresses IPv4: Unicast, broadcast, and multicast. IPv6: Unicast, multicast, and anycast. 6:Number of classes IPv4: IPv4 offers five different classes of IP Address. Class A to E. IPv6: IPv6 allows storing an unlimited number of IP Address. 7: VLSM support IPv4: IPv4 support VLSM (variable length subnet mask). IPv6: IPv6 does not offer support for VLSM. 8: Network Configuration IPv4: Networks need to be configured either manually or with DHCP. IPv4 had several overlays to handle Internet growth, which require more maintenance efforts. IPv6: IPv6 support autoconfigur

REST API

Image
REST API is an architectural style for an application program interface (API) that uses HTTP requests to access and use data. A request is sent from client to server in the form of a web URL as HTTP GET or POST or PUT or DELETE request. GET: The HTTP GET method is used to read (or retrieve) a representation of a resource. Example GET: Request for all Students. HTTP GET:/api/students POST: The POST verb is most often utilized to create new resources. Example POST: Request for Posting/Creating/Inserting Data HTTP POST:/api/students {“name”:”Aditya”} PUT: It is used for updating the capabilities. However, PUT can also be used to create a resource in the case where the resource ID is chosen by the client instead of by the server. PATCH: It is used to modify capabilities. The PATCH request only needs to contain the changes to the resource, not the complete resource. Example PUT or PATCH: Request for Updating Data at id=1 HTTP PUT or PATCH:/api/students/1 {“name”:”Rahul”}
