Cómo comprobar si un proxy es estático: IP, ASN y ubicación a lo largo del tiempo

# One check through the proxy: IP, network (org = ASN + name), country, city
curl -s -m 30 -x "http://USERNAME:[email protected]:7777" https://ipinfo.io/json

# 24 checks, one per hour, one line per check in ip-log.txt
PROXY="http://USERNAME:[email protected]:7777"
for i in $(seq 1 24); do
  printf '%s ' "$(date -u +%Y-%m-%dT%H:%M:%SZ)" >> ip-log.txt
  curl -s -m 30 -x "$PROXY" https://ipinfo.io/json | tr -d '\n' >> ip-log.txt
  echo >> ip-log.txt
  sleep 3600
done

# Count the distinct exit IPs and networks in the log (one line each = static)
grep -o '"ip": *"[^"]*"' ip-log.txt | sort | uniq -c
grep -o '"org": *"[^"]*"' ip-log.txt | sort | uniq -c

"""Log the exit IP, network and location of one proxy over time.

A static IP shows the same IP, network (ASN) and country in every row.
Install: python -m pip install requests
