The IPv4 Depletion Reality in Bangladesh Telecoms
With sky-rocketing leasing costs for IPv4 subnets, ISPs are forced into aggressive CGNAT ratios exceeding 1:64, creating severe connectivity drops in mobile banking and online gaming. IPv6 Dual-Stack offers the only sustainable technical solution.
DHCPv6 Prefix Delegation (PD) Architecture
By delegating a /64 or /56 prefix pool directly via PPPoE profiles, client optical routers assign native global public IPv6 addresses to internal home devices with zero NAT latency.
Native IPv6 Logging in fiberNox
fiberNox FreeRADIUS seamlessly provisions Framed-IPv6-Prefix attributes and stores full dual-stack IPDR session timestamps in compliance with BTRC regulatory audits.
Frequently Asked Questions (FAQ)
