Hi, This is confusing and appears to have been a transient error. We have (and historically have) had a feature that converts IP addresses to their routed prefix (using longest prefix matching). This looks like `"messages":[["info","IP address (159.138.184.0) has been converted to its encompassing routed prefix (159.138.184.0/24)"]]` in the JSON response. This is not present in your sample. I will ask a colleague to check how we handle a failure of a call to check for the longest prefix matching. ---

> [@ties](#): > > 159.138.184.0 Hi, ties From what I observed, it seems to be a temporary issue. After a while, querying a single IP address returned normal data, but the problem still doesn’t seem to be resolved. **curl --location --request GET “[https://stat.ripe.net/data/looking-glass/data.json?resource=14.137.164.1](https://stat.ripe.net/data/looking-glass/data.json?resource=14.137.164.1)” | jq | more** % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 524 100 524 0 0 2648 0 --:–:-- --:–:-- --:–:-- 2659 { “messages”: , “see\_also”: , “version”: “2.1”, “data\_call\_name”: “looking-glass”, “data\_call\_status”: “supported”, “cached”: false, “query\_id”: “20260902014325-e54c4041-52a2-43cf-b1eb-b4a06d572958”, “process\_time”: 119, “server\_id”: “app183”, “build\_version”: “v0.11.10-2026.08.31”, “pipeline”: “1403542”, “status”: “ok”, “status\_code”: 200, “time”: “2026-09-02T01:43:25.145158”, “data”: { “rrcs”: , “query\_time”: “2026-09-02T01:43:25”, “latest\_time”: “2026-09-02T01:42:29”, “parameters”: { “resource”: “14.137.164.1”, “look\_back\_limit”: 86400, “cache”: null } } } **curl --location --request GET “[https://stat.ripe.net/data/looking-glass/data.json?resource=14.137.164.0/24](https://stat.ripe.net/data/looking-glass/data.json?resource=14.137.164.0/24)” | jq | more** % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 155k 100 155k 0 0 674k 0 --:–:-- --:–:-- --:–:-- 674k { “messages”: , “see\_also”: , “version”: “2.1”, “data\_call\_name”: “looking-glass”, “data\_call\_status”: “supported”, “cached”: false, “query\_id”: “20260902014352-327eaaf0-553e-4e4b-99bb-48e10bedfb70”, “process\_time”: 98, “server\_id”: “app192”, “build\_version”: “v0.11.10-2026.08.31”, “pipeline”: “1403542”, “status”: “ok”, “status\_code”: 200, “time”: “2026-09-02T01:43:52.478382”, “data”: { “rrcs”: [ { “rrc”: “RRC01”, “location”: “London, United Kingdom”, “scope”: “LINX / LONAP”, “peers”: [ { “asn\_origin”: “136907”, “as\_path”: “8218 6461 1299 136907 136907 136907 136907 136907”, “community”: “8218:103 8218:20000 8218:20110”, “largeCommunity”: “”, “extendedCommunity”: “”, “last\_updated”: “2026-09-02T01:23:22.910000”, “prefix”: “14.137.164.0/24”, “peer”: “5.57.80.210”, “origin”: “IGP”, “next\_hop”: “5.57.80.210”, “latest\_time”: “2026-09-02T01:43:48.100000”, “community\_info”: {} }, { “asn\_origin”: “136907”, “as\_path”: “36924 1299 136907 136907 136907 136907 136907”, “community”: “1299:1000 1299:37000 1299:57000”, “largeCommunity”: “”, “extendedCommunity”: “36924:1”, “last\_updated”: “2026-09-02T01:24:06”, “prefix”: “14.137.164.0/24”, “peer”: “5.57.81.76”, “origin”: “IGP”, “next\_hop”: “5.57.81.76”, “latest\_time”: “2026-09-02T01:43:48.170000”, “community\_info”: { “regular”: { “1299:37000”: { “original”: “1299:37000”, “description”: “Asia+Pacific Customers” } }, “large”: {}, “extended”: {} } }, { “asn\_origin”: “136907”, “as\_path”: “48070 61049 174 1299 136907 136907 136907 136907 136907”, “community”: “”, “largeCommunity”: “”,
