What it is for

Recognise traffic from AWS, allow a region through a firewall, or tell cloud-hosted bots from residential visitors.

$curl -s https://proxyspace.pro/ip-ranges/aws.txt

# Is this address in AWS? (prints it if so)
echo 203.0.113.7 | grepcidr -f <(curl -s https://proxyspace.pro/ip-ranges/aws.txt)

Amazon Web Services IP ranges: questions

How many IP addresses does Amazon Web Services use?

The official list has 6,102 IPv4 prefixes covering 102,043,817 addresses and 3,287 IPv6 prefixes, in 43 regions; the largest is us-east-1 with 23M IPv4 addresses.

How often does the Amazon Web Services IP list change?

ProxySpace fetches it every day; the source was last updated on 2026-11-08. Rules built from it should be refreshed regularly, for example with a daily cron job that downloads the list again.

How do I check whether an IP belongs to Amazon Web Services?

Download the list and match the address against it, or use the IP lookup tool to see the network (ASN) an address belongs to.

Where are the IP ranges of other networks?

See the IP ranges page for every cloud provider and every country, or the Tailscale page for the 100.64.0.0/10 range.
