Summary

Gleim Internet

United States of America · AI-generated

business corporate aviation exam-prep

The AS handle GLEIM-ASN is held by Gleim Internet, Inc.

What it's used for

  • The space carries corporate infrastructure for Gleim, evidenced by the netname GRUNET-GLEIM-1 and reverse DNS pointing to teamgleim.com.
  • The inventory consists of a single IPv4 prefix, 209.251.141.0/24, with 256 addresses announced and only 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.

Notable

  • The registrant Gleim Internet, Inc. matches the AS holder, confirming direct ownership of the address space.
  • Gleim Internet, Inc. is the corporate entity behind Gleim Exam Prep, a major provider of study materials for accounting and other professional certification exams, and also operates Gleim Field in Gainesville, Florida.
  • The address inventory is minimal, consisting of one /24 block with no IPv6 prefixes, typical of a specialized business entity maintaining its own internal network.

Reputation

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: 453 networks and 1,848 prefixes, as published 2026-11-13. 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.
