IPv6

IPv6 has a much larger number of available addresses than IPv4 which allows all Internet-connected devices to have public addresses and outmodes floating IPs and NAT used with IPv4.

Pan-Net NFVI fully supports IPv6 and dual stack applications, including

  • Stateful autoconfiguration where an IPv6 address is assigned by DHCP

  • Stateless autoconfiguration using the EUI-64 addressing process (SLAAC)

  • Multiple addresses per interface

Networking based on IPv6 provides advantages over IPv4 such as

  • More efficient routing and packet processing due to shorter routing tables and omitted router checksum verification

  • Simplified network configuration by increased flexibility and auto-configuration capabilities

  • Stronger security through native IPSec support

Pan-Net tenants support IPv6 networking out-of-the-box. To use it, it is necessary to obtain IPv6 addresses from an ISP and configure DNS with necessary records. In a tenant, networks and subnets are configured for single IPv6 stack or dual stack addressing with OpenStack commands.
