AS11352 IOMAR-11352

IOMAR-11352 is Iomartcloud Inc., the US arm of the UK-headquartered iomart Group — a managed-hosting, cloud and colocation provider whose main network is [AS20860](https://asn.ipinfo.app/AS20860). This ASN carries iomart's American footprint.

What it's used for

Managed hosting and cloud, not access or transit. RIS sees 15 v4 prefixes / 7,424 addresses, 2 IPv6 prefixes (a 2606:f500::/32 plus a /36 out of it), and only 3 observed neighbours. That combination is diagnostic: a real transit carrier would show hundreds of neighbours against this address count, so the space is being consumed by servers rather than resold. The v4 inventory is dominated by a /20 and two /22s carved into /24s — a rack-and-VLAN allocation pattern typical of a hosting estate spread across a few sites.

Notable

The prefix registrants look scattered at first glance and then all resolve to the same group. 75.98.208.0/20 and 75.98.216.0/22 register as IOMART-US-CA1, 74.117.184.0/22 as IOMART-US-VA1 — California and Virginia sites — while the European blocks (212.38.176.0/23, 5.187.27.0/24, 212.38.184.0/24) sit under iomart's RIPE maintainers GB10488-RIPE-MNT and IOMART-MNT. Two RIRs, several handles, one company: this is a legitimate multi-region operator, not the multi-registrant pattern that signals leased space.

Interesting

Reverse DNS confirms the family tree — va1-grid-01-03.iomartcloud.com names the Virginia grid, while other addresses answer under no-ptr.as11352.net and no-ptr.as20860.net, the same house convention pointing back at iomart's UK ASN.
