Free IPv6 static IP vs rolling your own on a VPS: which should you do?

Short answer: IPv6 addresses are genuinely free, and you can absolutely bind one on a cloud VPS from AWS or DigitalOcean and use it as your static IP. The address was never the expensive part. What costs you is everything around it: keeping a server up 24/7, patching it, absorbing reboots and migrations that break your whitelist, and the extra network hop if the server is not in Mumbai. For a small personal setup a DIY VPS works fine. For live trading you rely on, a managed dedicated IP removes the parts that quietly go wrong.

This question comes up constantly: "IPv6 is free, I can get it from AWS, so why would I use a provider?" It is a fair question and the honest answer is that both are valid. Here is the real trade-off.

The DIY route: a VPS with its own IPv6

When you spin up a cloud VPS you typically get a block of IPv6 addresses with it. A DigitalOcean droplet, for example, hands you a /124, which is 16 IPv6 addresses. You bind them to the server and route your traffic out through one of them, and that becomes your static IP. If you wanted to, one droplet like that could serve several people, each egressing from a different address in the block. The mechanism is sound and it genuinely works.

So the address is free. But you are now running a server, and that is where the real costs are.

What DIY actually costs you

• The VPS is not free. The IPv6 is free; the instance you have to run to use it is not. You pay for the box every month whether or not you are trading.
• Uptime is now your job. One droplet is a single point of failure. A reboot or provider maintenance drops your connection, and if you are mid-session that is a missed or stuck order.
• The IP is tied to the instance. Rebuild, resize, or migrate the droplet and its addresses can change, which forces you to re-whitelist with your broker. A static IP that quietly changes is not really static.
• Latency depends on the region. DigitalOcean's India region is in Bangalore, not Mumbai where the exchanges sit, so you eat an extra hop. For latency-sensitive algos that matters.
• Shared box, shared risk. If you put several users on one droplet, they share CPU, bandwidth and one operating system. A noisy neighbour or a compromise affects everyone on it.
• You are now the custodian. Running a proxy or egress server means you own the hardening, patching and abuse monitoring, and you become a target.
• No easy redundancy. SEBI's framework lets you whitelist a secondary IP for failover. One droplet cannot really give you a clean second address in a different location.

None of these are dealbreakers for a hobby setup. They are simply the reasons the DIY route stops being worth it once real money is riding on the connection.

The managed route: a dedicated IP you do not run

A managed dedicated static IP flips the equation. You do not spin up or maintain anything. You point your trading client at the address, whitelist it once, and trade from a laptop on home wifi if you like. There is no server for you to keep alive.

The difference on our end is scale and ownership. Instead of the per-droplet allocation you get from a VPS, TrueIP runs its own routed block of addresses, so the IPs are ours rather than tied to one provider's instance, they sit in Mumbai next to the exchanges, and there is nothing for you to patch or reboot. You get a fixed address that stays fixed, and we handle the annoying part.

And because IPv6 is not scarce, we do not charge for the address either. It is free with us too, the same as it is on AWS, except you are not running the server around it.

So which should you choose?

Use a DIY VPS static IP if:

• You are comfortable running and hardening a server.
• It is a personal, low-stakes setup and occasional downtime is fine.
• You already run a VPS for something else and can reuse its IPv6.

Use a managed dedicated IP if:

• The connection is for live trading you cannot afford to have drop.
• You want a Mumbai-based address for lower latency to broker APIs.
• You would rather not own patching, uptime, and re-whitelisting when a rebuild changes your IP.
• You want the option of a whitelisted secondary IP for redundancy.

Both get you a static IP. The DIY route makes the free address your problem to keep alive; the managed route makes it someone else's. For a deeper split of the two concepts, see static IP vs VPS for algo trading, and to check your broker will even accept IPv6, see which Indian brokers support IPv6.
