AS42003 OGEROASN lookup: IP ranges, prefixes and network type
AS42003 is the autonomous system number (ASN) announced by OGERO. It announces 13 prefixes, 126,976 IPv4 addresses in total. Every address inside those ranges is routed by this operator, which is what makes the number the shortest answer to who runs a given address.
AS42003 at a glance
| Organisation | OGERO |
|---|---|
| Autonomous system | AS42003 |
| Network type | UnclassifiedThe registered name carries no indication either way, so nothing is claimed. |
| IPv4 prefixes | 10 |
| IPv6 prefixes | 3 |
| IPv4 addresses | 126,976Summed across every announced prefix. IPv6 is not counted; the numbers are meaningless at that scale. |
| In known VPN ranges | 0 of 10 prefixes |
| In known datacenter ranges | 0 of 10 prefixes |
The last two rows are a second opinion, counted against the X4BNet VPN and datacenter range lists rather than read off the operator name. A network with most of its prefixes in the VPN list is carrying anonymised traffic whatever it calls itself.
Sample prefixes
The largest ranges OGERO announces, biggest first. These are a sample and not the full routing table: 13 prefixes do not fit on a page, and the ones worth showing are the ones most traffic comes from.

What AS42003 means for detection
Registry data does not say what kind of network OGERO runs, and this page will not guess. Ownership alone cannot settle it: the name is the only clue an ASN carries about purpose, and this one carries none. A single address on it can still be classified, because that uses behaviour and range membership rather than the operator's name. Run one below and see what comes back.
The verdict for a single address is never settled by the ASN alone. It is the starting point, and IP Detection adds range membership, behaviour and history on top of it before it answers.
