When calculating hosts' IP addresses, 2 IP addresses are decreased because they cannot be assigned to hosts, i.e. the first IP of a network is network number and the last IP is reserved for Broadcast IP. Class A Address. The first bit of the first octet is always set to 0 (zero). … IPv4 offers 12 header fields whereas IPv6 offers 8 header fields. IPv4 supports broadcast whereas IPv6 doesn’t support broadcast. IPv4 has checksum fields while IPv6 doesn’t have checksum fields; IPv4 supports VLSM (Virtual Length Subnet Mask) whereas IPv6 doesn’t support VLSM. Informatique : Apprendre les bases du réseau avec ce cours : IPv4, IPv6, TCP/IP, translation d'adresses avec le NAT, résolution DNS, adresses MAC, etc. 18/12/2019 · But IPv6 also has larger packets, which may make it slower for some use cases. What really makes a difference at this point is that IPv4 networks are mature and thus highly optimized, more so than IPv6 networks. So with time and tuning, IPv6 networks will get faster.
