BDIX-Connected Bandwidth vs International Bandwidth Explained

Hosting connectivity in Bangladesh usually comes in two flavours: local BDIX bandwidth and international bandwidth (often called IIG). They behave very differently, and knowing which carries your traffic explains a lot about your site's local speed. Let us break it down.

What is BDIX bandwidth?

BDIX bandwidth carries traffic between networks inside Bangladesh, over the local exchange. Because it stays in-country, it is typically fast, low-latency and plentiful — ideal for reaching a domestic audience.

What is international bandwidth?

International bandwidth carries traffic to and from the rest of the world, through international gateways. It is essential for global reach, but it travels much further, so it has higher latency for local users and is generally a more constrained resource.

Why the difference matters

• Local traffic on BDIX is fast and efficient — great for Bangladeshi visitors, downloads and streaming.
• International traffic is necessary for overseas visitors but adds distance and delay for local ones.

This is exactly why BDIX hosting feels so quick locally: it serves domestic visitors over local bandwidth rather than sending them across international links. If you are new to the concept of bandwidth generally, see what bandwidth is.

What this means for your hosting choice

A well-connected BDIX host offers strong local bandwidth for your Bangladeshi audience and international bandwidth so the rest of the world can still reach you. The balance you need depends on where your visitors are. VernalWeb's BDIX-connected hosting and colocation is provisioned with local peering and international uplink together.

Frequently asked questions

Is BDIX bandwidth "unlimited"?

No connection is truly unlimited, but local BDIX bandwidth is typically far more generous than international bandwidth, which is why local downloads and streaming run so smoothly. Always check a plan's specifics.

Does international bandwidth still matter with BDIX hosting?

Yes — it carries your overseas visitors and any content your server fetches from abroad. A good BDIX host provides both. The two serve different audiences.

Which bandwidth affects my local visitors' speed?

Local BDIX bandwidth. For a Bangladeshi audience, strong BDIX connectivity is what delivers the fast, low-latency experience.
