About this network
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. 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.
