Market research: how many hosters support IPv6
The number of free IPv4 addresses is rapidly decreasing, however, no one is in a hurry to switch to the 6th version of the protocol. There is no exact estimate of the deadlines for the complete exhaustion of IPv4, and day X is constantly being postponed. Due to the shortage of IPv4 addresses, their market value is growing rapidly and, if earlier IP addresses at retail could be bought for about $ 1, now there are almost no such offers and hosters are asking on average from three to five dollars for one address, otherwise and more.
IPv4 was written back in 1981, but it is still in use today. IPv4 uses 32-bit addresses, therefore the maximum number of unique IP addresses is 2 ^ 32 = 4,294,967,296 addresses.
It would seem that 4 billion is a lot, but in reality there are very few free addresses left.
IPv4 should be replaced by protocol of the 6th version - IPv6. This protocol uses 128-bit addresses, therefore the maximum number of IPv6 addresses is 3.4 × 10 ^ 38 = very many.
The main reason for the slow transition to the 6th version of the protocol, as it seems to me, is the sluggishness of “home” providers. Website owners are well aware that spending time and money setting up IPv6 is stupid, since almost no one will use this version of the protocol, which means it is better to spend resources on something else.
The reasons why home providers do not implement IPv6 are about the same: there are very few sites that support this protocol, and users will obviously not pay extra for such a service, so there is no point in switching for them. The result is a vicious circle, which, it seems to me, should be opened by both hosters and website owners. As soon as most sites start working through IPv6, then home providers will begin to work faster in this direction.
A filter by the availability of IPv6 for hosts on vds.menu shows that this protocol supports less than half of hosters: 242 tariffs claim IPv6 support , 406 do not. In my opinion, these are pretty sad numbers, since if less than half of the hosters offer IPv6 addresses, then the percentage of those who use them is even lower.
However, I wondered how many hosters use IPv6 on their own sites. Having written a simple script, I saw a terrifying situation: out of 71 hosters, only 9 support IPv6 on their sites (13%). To somehow encourage these hosters, I decided to write their domains in this topic.
