If you’re choosing a server for a website, app or game that serves Bangladeshi users, you’ve probably seen two terms thrown around: BDIX and IIG. They sound similar, but they affect your speed, latency and monthly bill in very different ways. Here’s a plain-English breakdown — and which one you should actually pick.

What is BDIX?

BDIX (Bangladesh Internet Exchange) is the local internet exchange point where Bangladeshi ISPs connect to each other. When traffic travels over BDIX, it stays inside Bangladesh — it never needs to leave the country and come back. That’s why BDIX connections are so fast: data takes the shortest possible route.

For a server, being BDIX-connected means a visitor on Grameenphone, Banglalink, Robi or any local ISP can reach your server directly through the exchange, typically in under 2ms. This is why BDIX VPS hosting is the go-to choice for local websites, e-commerce stores and streaming platforms targeting Bangladesh.

What is IIG?

IIG (International Internet Gateway) is the licensed gateway that connects Bangladesh to the global internet through submarine cables. Every time you visit a foreign website, your traffic passes through an IIG. It’s essential — but it’s slower and more expensive than local peering because data has to travel internationally and back.

An IIG VPS is optimised for international routing. It’s the right tool when your audience is outside Bangladesh, but it’s overkill (and pricier) when most of your visitors are local.

BDIX vs IIG: Key Differences at a Glance

BDIX vs IIG Speed: Which Is Faster?

For a Bangladeshi visitor, BDIX is dramatically faster. A request that stays on BDIX completes in a few milliseconds, while the same request routed internationally adds a full round-trip across the globe — often 100ms or more. Multiply that across every image, script and API call on your page, and the difference becomes very visible: faster loads, lower bounce rates and better Google rankings.

You can verify this yourself with a BDIX speed test: ping a local BDIX-connected server versus an international one and compare the response times.

Cost: Why BDIX Bandwidth Is Cheaper

International bandwidth is the single biggest cost in Bangladeshi hosting. Because BDIX traffic never touches international cables, providers can offer it far cheaper — which is why most BDIX VPS plans include unlimited local bandwidth at no extra charge. Your international (IIG) usage stays separate, so you only pay for what you actually use overseas.

Which One Should You Choose?

Choose a BDIX VPS if…

• Your website or app is built for Bangladeshi users
• You run an e-commerce store, news portal or streaming service serving local customers
• You want the fastest loading speed and lowest latency in Bangladesh
• You want unlimited local bandwidth without overage fees

Choose an IIG VPS if…

• Your audience is primarily international
• You need to reach overseas APIs, clients or backup targets constantly

Frequently Asked Questions

Is BDIX free?

BDIX is a peering exchange, not an internet service. Your ISP or host peers with it so that local traffic stays local. For end users, BDIX bandwidth is usually far cheaper than international bandwidth — and many BDIX VPS plans include it unlimited.

Can I use both BDIX and IIG on one server?

Yes. Most servers have both: BDIX for local traffic and an IIG allocation for international traffic. You get the best of both worlds.

How do I test if my site is on BDIX?

Run a ping or traceroute from a Bangladeshi ISP. If the route stays inside Bangladesh with single-digit millisecond latency, you’re going through BDIX.
