Report for IP: 209.50.164.225

• Spamhaus DROP — Spamhaus DROP lists netblocks hijacked or leased by professional spam and cybercrime operations. Very low false-positive rate: no legitimate traffic is expected from these ranges.
• FireHOL level1 — FireHOL level1 merges DShield, Spamhaus DROP, bogon ranges and Feodo botnet servers into one curated list built for very low false positives. When DShield or Spamhaus DROP also match, this one adds no independent evidence, since it already contains them.

Curated, low-false-positive lists match, so this is a high-confidence bad address.
