How to throttle the FCC to dial up modem speeds on your website using Nginx
# The blog post that started it all: https://neocities.org/blog/the-fcc-is-now-rate-limited
#
# Current known FCC address ranges:
# https://news.ycombinator.com/item?id=7716915
#
# Confirm/locate FCC IP ranges with this: http://whois.arin.net/rest/net/NET-165-135-0-0-1/pft
#
# In your nginx.conf:
location / {
if ( $remote_addr ~* 192.133.125.0/24 ) {
limit_rate 3k;
}
if ( $remote_addr ~* 165.135.0.0/16 ) {
limit_rate 3k;
}
if ( $remote_addr ~* 192.104.54.0/24 ) {
limit_rate 3k;
}
if ( $remote_addr ~* 4.21.126.0/24 ) {
limit_rate 3k;
}
if ( $remote_addr ~* 65.125.25.64/26 ) {
limit_rate 3k;
}
if ( $remote_addr ~* 208.23.64.0/25 ) {
limit_rate 3k;
}
# put the serve files or proxy_pass code here.
