IPv4 vs IPv6 Explained

IPv4 vs IPv6 at a glance — comparison table

Address size and abundance. IPv4 uses 32-bit addresses — about 4.3 billion, a pool exhausted since 2011 — while IPv6 uses 128 bits: 340 undecillion addresses.

Practical notes for site owners: CIDR notation sizes both protocols' networks, and SLAAC lets IPv6 hosts auto-configure addresses without DHCP. Most Indian hosting — including WebJi® datacenter locations — serves dual-stack, so your site answers on both protocols without extra work.

Address space — why IPv4 ran out

How this plays out with IPv4: settings that look cosmetic usually decide page speed and uptime under real traffic. The defaults WebJi® ships are tuned for Indian network conditions, and support can review your setup on request.

How IPv6 addresses look and shorten

Change one setting at a time, and undo it if the result is wrong before you try the next.

NAT vs end-to-end connectivity

Two practical notes on 32-bit vs 128-bit addressing: it interacts directly with caching and database response, and misconfiguration is the most common cause of 'hosting is slow' tickets. WebJi® support checks it as part of standard migrations.

Dual-stack hosting — serving both

Dual-stack hosting — serving both. Do the change this heading names on one site first, then check it in a private browser window or in the mail client, depending on the topic. Change one setting at a time, and undo it if the result is wrong before you try the next.

Enabling IPv6 on your VPS or website

On AAAA record, the honest summary is that defaults matter more than brand names — a well-set budget plan outranks a mis-tuned premium one. WebJi® documents its defaults openly and adjusts them per ticket when workloads need it.
