Summary
DataBridge Sites
hosting datacenter business
The AS handle MPDCOL is held by DataBridge Sites, LLC.
What it's used for
- The address space carries static data center infrastructure, evidenced by reverse DNS entries such as
static.dca1.net.agiledatasites.comandstatic.net.bytegrid.com. - The network announces 7936 IPv4 addresses across 13 prefixes and 1 IPv6 prefix, while maintaining only 5 observed neighbours, a ratio indicative of a hosting or business network rather than a transit provider.
Notable
- Registrants include DataBridge Sites, LLC, QuestHost.com, LLC, and American Registry for Internet Numbers, with netnames like
AGILE-IPV4-01andGORILLANODEreflecting the operator's data center focus. - The address inventory is finely subdivided into multiple /23 and /24 blocks, consistent with site-by-site segmentation for a corporate data center estate.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,781 prefixes, as published 2026-10-16. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
