In the August 2023 survey we received responses from 1,093,748,332 sites across 255,459,417 domains and 12,162,471 web-facing computers. This reflects a loss of 7.5 million sites and 259,924 domains, and a gain of 36,515 web-facing computers.

OpenResty had the largest growth this month, gaining 2.1 million sites (+2.29%) and 98,319 domains (+0.24%). Its market share now stands at 8.71% of sites and 15.8% of domains seen by Netcraft, up by 0.25pp and 0.05pp respectively. Within the top million sites, OpenResty also had the largest gain of 78 sites, increasing its market share by 0.01pp to 1.02%.

Microsoft saw the largest loss this month, losing 3.1 million sites (-9.52%), 123,295 domains (-1.74%) and 10,571 computers (-0.89%). Microsoft now accounts for 2.73% of sites seen by Netcraft, down by 0.27pp. Cloudflare also lost 2.1 million sites (-1.73%) and 874,997 domains (-3.36%) this month. However, Cloudflare still holds a substantial market share of 10.8% of ites and 9.86% of domains, down by -0.12pp and -0.33pp respectively.

Apache and nginx also experienced losses in sites (-1.0 million and -561,031 respectively), but remained steady in market share: nginx now accounts for 23.7% of sites seen by Netcraft, up by 0.11pp, and Apache's market share increased by 0.05pp to 20.9% of sites.

AWS announces IPv4 pricing change

AWS has announced that in-use public IPv4 addresses will no longer be free of charge. From February 2024, users of AWS-owned public IPv4 addresses within their VPC will be charged at a flat rate of one half-cent per hour, or roughly $3.75 per month, reflecting the value of an IPv4 address within an increasingly scarce supply.

Netcraft saw just over 2 million active web-facing IPv4 addresses at Amazon in August. At list price, these would provide Amazon around $90M in annual revenue. While useful, this is a fairly crude estimate: many of these detected IP addresses will not be chargeable—for example those used by CloudFront or S3—and some chargeable IPv4 addresses will not be publicly observable.

The change will not impact Bring your own IP addresses (BYOIP) owned by customers. Hilco Streambank reports recent auction results at around $30-$40 per IPv4 address, which may make BYOIP a more appealing option for larger users. To reduce the impact of the change upon individuals and small organizations, the AWS Free Tier will include 750 hours of public IPv4 address usage per month.
