Warning: AS61337 (ECOM-AS) announces 12 IPv4 and 1 IPv6 prefixes. 3 warnings

Holder	ECOM-AS Single Mode Networks Ltd
Allocation	RIPE NCC, United Kingdom (GB), allocated 2012-11-19

What to fix

Warning
3 of 13 announced prefixes have no ROA (RPKI not found): 83.150.249.0/24, 83.150.250.0/23, 193.26.23.0/24.

Without a ROA, networks cannot tell your routes from a hijack.

Fix: Create a ROA for each at your RIR portal, with origin AS61337 and a max length equal to the prefix length:
```
83.150.249.0/24 AS61337 max-length /24
83.150.250.0/23 AS61337 max-length /23
193.26.23.0/24 AS61337 max-length /24
```
Open in RPKI / ROA validator Guide
Warning
1 of 13 announced prefixes have no IRR route object: 83.150.250.0/23.

Many networks build their prefix filters from IRR data; without route objects some of them drop the routes.

Fix: Create route (IPv4) and route6 (IPv6) objects with origin AS61337 in your RIR’s IRR database (or RADB).
```
route: 83.150.250.0/23
origin: AS61337

Warning

No public NOC, policy or technical contact.

Other networks use these addresses to set up peering and to reach you during an incident.

Fix: Add a role contact (for example noc@ or peering@ an address you monitor) with visibility Public.
