--- title: Monitoring IP Ranges for Your Allowlist description: Find WatchFor monitoring server IP addresses and ranges. Whitelist our IPs in your firewall to allow monitoring of your services behind firewalls and private networks. canonical: https://watchfor.io/ip-ranges --- # Monitoring IP ranges When your servers, databases or internal APIs live behind a firewall, our monitors can't reach them โ€” until you let us in. Add these IPs to your allowlist and checks run against your private infrastructure just like they do for anything public. The list stays stable, and every address is provably ours (that's what [/bot](/bot) is for), so you're not opening a hole for some mystery range. ## Grab the list [/ips.jsonStructured, with locations](/ips.json)[/ipv4.txtPlain, one per line](/ipv4.txt)[/ipv6.txtPlain, one per line](/ipv6.txt) Copy all IPv4 Copy all IPv6 Copy everything Static โ€” but re-fetch when you automate These addresses don't change on a whim, but we add regions over time. If you allowlist programmatically, pull [/ips.json](/ips.json) (or the .txt files) on a schedule rather than hard-coding, so new locations are picked up automatically. ## Every location, by region ### Europe Copy Europe Location IPv4 IPv6 Hostname ๐Ÿ‡ซ๐Ÿ‡ท Paris , France 15.236.177.94 2a05:d012:c19:3401:4dc9:840d:8f8d:85d0 paris-1.fr.probe.watchfor.io ๐Ÿ‡ฉ๐Ÿ‡ช Frankfurt , Germany 35.157.172.211 2a05:d014:155e:5600:c3a5:473e:e9d7:4fcb frankfurt-1.de.probe.watchfor.io ๐Ÿ‡ฑ๐Ÿ‡น Vilnius , Lithuania 85.206.149.28 โ€” vilnius-1.lt.probe.watchfor.io ๐Ÿ‡ฑ๐Ÿ‡น Vilnius , Lithuania 80.209.238.252 2a02:7b40:50d1:eefc::1 vilnius-2.lt.probe.watchfor.io ๐Ÿ‡ช๐Ÿ‡ธ Madrid , Spain 15.217.52.23 2a05:d011:f31:a700:6ab:26fc:e1b6:a2a madrid-1.es.probe.watchfor.io ๐Ÿ‡ธ๐Ÿ‡ช Stockholm , Sweden 13.63.231.185 2a05:d016:db4:1200:e052:7feb:a7dd:1cb8 stockholm-1.se.probe.watchfor.io ๐Ÿ‡ฌ๐Ÿ‡ง London , United Kingdom 18.132.86.229 2a05:d01c:d1f:1b00:8c65:d5a7:3b55:f96b london-1.gb.probe.watchfor.io ### North America Copy North America Location IPv4 IPv6 Hostname ๐Ÿ‡จ๐Ÿ‡ฆ Montreal , Canada 16.54.175.65 2600:1f11:26:9200:5230:88f5:ca1c:8dba montreal-1.ca.probe.watchfor.io ๐Ÿ‡ฒ๐Ÿ‡ฝ Querรฉtaro , Mexico 78.14.142.185 2600:1f17:428c:c500:8ebb:1f23:21f7:62b4 queretaro-1.mx.probe.watchfor.io ๐Ÿ‡บ๐Ÿ‡ธ Ashburn , United States 52.73.13.30 2600:1f18:7b53:2800:f95c:9c84:6f85:e3e7 ashburn-1.us.probe.watchfor.io ๐Ÿ‡บ๐Ÿ‡ธ Columbus , United States 18.226.195.23 2600:1f16:9d5:ec00:310f:fa1:98de:3f60 columbus-1.us.probe.watchfor.io ๐Ÿ‡บ๐Ÿ‡ธ Portland , United States 34.210.233.0 2600:1f14:3b0c:6400:914:8212:717f:84b8 portland-1.us.probe.watchfor.io ### South America Copy South America Location IPv4 IPv6 Hostname ๐Ÿ‡ง๐Ÿ‡ท Sรฃo Paulo , Brazil 18.230.13.42 2600:1f1e:a43:c500:76cf:93f:7a49:9f8e sao-paulo-1.br.probe.watchfor.io ### Asia Copy Asia Location IPv4 IPv6 Hostname ๐Ÿ‡ฎ๐Ÿ‡ณ Mumbai , India 3.111.4.15 2406:da1a:1082:bd00:3d80:8d20:9d2f:5b18 mumbai-1.in.probe.watchfor.io ๐Ÿ‡ฎ๐Ÿ‡ฉ Jakarta , Indonesia 16.79.55.179 2406:da19:45b:cd00:909b:f6b4:f77e:51de jakarta-1.id.probe.watchfor.io ๐Ÿ‡ฏ๐Ÿ‡ต Tokyo , Japan 13.114.238.105 2406:da14:13bb:ce00:f883:cbfe:84e7:e1a9 tokyo-1.jp.probe.watchfor.io ๐Ÿ‡ธ๐Ÿ‡ฌ Singapore , Singapore 13.250.143.183 2406:da18:1863:b400:fb92:3b38:6bdd:8386 singapore-1.sg.probe.watchfor.io ### Middle East Copy Middle East Location IPv4 IPv6 Hostname ๐Ÿ‡ฎ๐Ÿ‡ฑ Tel Aviv , Israel 16.164.39.228 2a05:d025:f8:fa00:fe40:7f04:148e:1f95 tel-aviv-1.il.probe.watchfor.io ### Africa Copy Africa Location IPv4 IPv6 Hostname ๐Ÿ‡ฟ๐Ÿ‡ฆ Cape Town , South Africa 13.244.54.44 2406:da11:f61:f300:c9c:e64a:61d6:e80e cape-town-1.za.probe.watchfor.io ### Oceania Copy Oceania Location IPv4 IPv6 Hostname ๐Ÿ‡ฆ๐Ÿ‡บ Sydney , Australia 52.62.237.155 2406:da1c:1682:5900:df7:d42c:8b58:f39e sydney-1.au.probe.watchfor.io ๐Ÿ‡ณ๐Ÿ‡ฟ Auckland , New Zealand 3.103.20.111 2406:da12:8bb0:3f00:9f31:99ac:aed7:33fe auckland-1.nz.probe.watchfor.io ## Automating or verifying?
