Summary

SD Data Center

United States · AI-generated

hosting infrastructure business

Five company names across twenty-five blocks, and an IPv6 announcement that tiles itself.

What it's used for

  • A hosting and colocation network. 27,904 addresses across 25 IPv4 prefixes plus 8 IPv6 prefixes, with 128 observed BGP neighbours.

Notable

  • Blocks registered to SD Data Center include 164.153.0.0/20, 209.151.192.0/21, 74.117.144.0/22 and 162.217.148.0/22.
  • 209.114.192.0/20, 209.114.208.0/21 and 209.114.220.0/22 register to Fiber Plus, Inc under the netname FIBERPLUS.
  • 205.149.128.0/21 and 205.149.136.0/21 register to Creative Network Innovations, Inc. under CNI-WEB.
  • 103.102.8.0/22 registers to an Australian company under the netname SATCOM-AU, with an incident response team object alongside the registrant.
  • The IPv6 space includes 2401:dac0::/32, 2a09:6d80::/32, and 2604:2ec0::/37 followed by a ladder of /37, /36, /35, /34 and /33.
  • The one address that answered gave 254-197-151-209.us.zerolayer.net.

Interesting

  • That 2604:2ec0 ladder covers the same space twice over in halves, each prefix taking exactly what the previous ones left. It is the same aggregate expressed as separate announcements, which lets each half be steered on its own path.
  • One netname carries an incident response object, a record type that exists in some registries and not others. A hosting company holding blocks under several registries' conventions has been buying address space wherever it was available rather than from one source.
  • The one reverse name that resolved reverses the address and ends in a sixth brand. A single colocation floor can carry a stack of company names, none of which the customer ever sees.

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 1,783 prefixes, as published 2026-10-17. 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.
