Website is extremely slow.

1.5 hours and I have failed to get through Global Uni cast Addresses as the video just bugs out. The questions in video only show half and refreshing the page takes 10 minutes.

I am running 100MB d/load and u/load and all other sites work.

IPv6 was developed to overcome the limitations of the IPv4 addressing protocol, specifically, the limited number of available IP addresses. IPv4 uses a 32-bit address space, which allows for approximately 4.3 billion unique addresses (2³²). In contrast, IPv6 uses a 128-bit address space, providing about 3.4 × 10³⁸ unique addresses.
