IPv4 vs IPv6 Kya Hai? Complete Guide

IPv4 aur IPv6 Kya Hota Hai?

Internet par har device ka ek unique address hota hai. Isko IP address kehte hain. Jab aap Google ya kisi aur website par jaate hain, toh aapka device isi address se communicate karta hai. Pehle sirf IPv4 use hota tha. Lekin internet users badhne ki wajah se IPv6 bhi banana pada.

IPv4 Address Ki Kahani

IPv4 internet ka sabse pehla version hai jo bade paimane par use hua. Yeh 32-bit ka address hota hai. Isme numbers dots (.) se separated hote hain. Jaise ki 192.168.1.1. Iski total limit lagbhag 4.3 billion devices ki thi. Lekin aaj ke samay me duniya me smartphones, laptops, smart TVs aur smart appliances bahut zyada hain. Isliye IPv4 addresses khatam hone lage.

IPv6 Kyon Zaroori Ho Gaya?

Jab IPv4 addresses kam padne lage, tab Internet Engineering Task Force ne IPv6 banaya. Yeh 128-bit ka address hota hai. Isme numbers aur letters dono hote hain jo colon (:) se separated hote hain. Jaise ki 2001:0db8:85a3:0000:0000:8a2e:0370:7334. Iski capacity itni badi hai ki humari dharti ke har ek atom ke liye kai IP addresses mil sakte hain. Ab Apple aur doosri companies bhi apne devices me default IPv6 use karti hain.

IPv4 aur IPv6 Me Mukhya Antar

Dono versions me sabse bada antar address size ka hai. IPv4 chhota hai aur IPv6 bahut bada hai. IPv6 me security features pehle se built-in aate hain. Jabki IPv4 me extra security add karni padti hai. IPv6 speed ke mamle me bhi behtar hai kyunki isme routing aur packet processing zyada asan hoti hai. Network administrators ke liye IPv6 manage karna thoda naya ho sakta hai, par long term me yeh hi future hai.

Kaun Sa Version Behtar Hai?

Agar aap aajkal ka internet use kar rahe hain, toh aap dono ka m मिश्रण dekh rahe hain. ISP (Internet Service Providers) dheere-dheere IPv6 par shift ho rahe hain. Kuch purane servers aaj bhi sirf IPv4 support karte hain, isliye dono sath me chal rahe hain. Aane wale samay me IPv6 hi poori tarah se raj karega kyunki IoT (Internet of Things) devices ko itne bade address pool ki hi zaroorat hai.
