Summary

Southern Data Center

United States of America · AI-generated

business datacenter us

SHAIKH-CORP is the AS handle for Southern Data Center.

What it's used for

  • The space carries a single IPv4 block, 148.59.34.0/23, with the netname NET148 and registrant Various Registries (Maintained by ARIN).
  • The AS announces 512 IPv4 addresses and 1 IPv6 prefix (2602:fe3f::/34) while maintaining only 1 observed neighbour, a ratio consistent with a small, self-contained business or data center estate rather than a transit provider.

Notable

  • The RDAP registrant for the announced prefix is Various Registries (Maintained by ARIN), which differs from the AS holder name SHAIKH-CORP or Southern Data Center.
  • The address inventory is minimal, consisting of a single /23 IPv4 block and a single /34 IPv6 prefix, indicating a tightly scoped internal or dedicated infrastructure footprint.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
