Summary

MRC Global (US) Inc.

United States of America · AI-generated

business industrial distribution corporate

The AS handle MRCGLOBAL-AS1 is held by MRC Global (US) Inc.

What it's used for

  • The address space carries corporate infrastructure for an industrial distributor, evidenced by the netname MRCGLOBAL-NET-1 and registrant MRC Global (US) Inc.
  • The inventory consists of 768 IPv4 addresses across 2 prefixes, with 3 observed neighbours, indicating a small internal corporate estate rather than a transit or access network

Notable

  • Registrants for both announced prefixes agree with the announcer, listing MRC Global (US) Inc. as the registrant for MRCGLOBAL-NET-1
  • The address inventory is finely subdivided into two small blocks, consistent with site-by-site segmentation for a corporate entity

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
