BERNER, Circuit Judge:

Amir Golestan was the founder and CEO of Micfo, LLC, a technology company.

Golestan pled guilty, on behalf of himself and on behalf of his company, to 20 counts of

wire fraud for fraudulently obtaining and reselling Internet Protocol addresses. After the

guilty pleas had been entered, Golestan moved to withdraw them, arguing that intervening

Supreme Court precedent invalidated the theory of prosecution for the wire fraud

convictions. The district court denied Golestan’s motion.

Golestan also maintains that the district court erred in failing to advise him of the

immigration consequences of his guilty plea and that his counsel was ineffective for failing

to advise him of those consequences. Separately, Micfo asserts that Golestan lacked the

requisite authority to enter guilty pleas on its behalf.

We affirm the judgments of conviction for both Golestan and Micfo.

I. Factual Background

A. IP Addresses and ARIN

This case concerns Internet Protocol (or IP) addresses. An IP address is a unique

numeric label assigned to each device, such as a computer or smartphone, that connects to

the Internet to send and receive information. In the United States, a single nonprofit

organization, the American Registry for Internet Numbers (ARIN), is responsible for

administering, allocating, and assigning IP addresses. When an individual or an entity

wants to obtain an IP address, it submits a request to ARIN. An analyst then reviews the

request and assigns a new IP address or transfers an existing one. Recipients are required

3 USCA4 Appeal: 23-4592 Doc: 84 Filed: 08/22/2025 Pg: 4 of 21

to enter into a Registration Services Agreement with ARIN prior to being assigned IP

addresses.

There are several versions of IP addresses, most recently version four, IPv4, and

version six, IPv6. IPv4 addresses are considered to be more valuable than their IPv6

counterparts principally due to their compatibility with existing networks and

infrastructure, which were designed with IPv4 in mind. IPv4 addresses are limited.

Although the global pool of free IPv4 addresses was exhausted in 2011, ARIN still had its

own pool of IPv4 addresses. As a result of the high demand for IPv4 addresses, “ARIN

often required justification and customer identification for additional IPv4 address blocks”

to verify the validity of IPv4 requests. J.A. 22. 1 ARIN eventually exhausted its allocation

of free IPv4 addresses in 2015. Although a secondary market now exists outside of ARIN

to purchase, sell, and transfer IPv4 addresses, ARIN maintains a role in this process by

overseeing the transfer of IP addresses from user to user.

B. Criminal Scheme

Amir Golestan was the owner and CEO of Micfo, LLC (Micfo). Micfo purported to

provide hosting services to Internet providers and businesses to allow these entities to

display their websites on the Internet. This sometimes required Micfo to allocate IP

addresses to its customers.

Initially, Micfo requested IPv4 addresses lawfully and in accordance with ARIN’s

policies and procedures. By 2014, however, Micfo began to engage in a criminal scheme

1 Citations to “J.A.” refer to the Joint Appendix filed by the parties in this appeal. 4 USCA4 Appeal: 23-4592 Doc: 84 Filed: 08/22/2025 Pg: 5 of 21

to obtain IP addresses from ARIN. Golestan and Micfo created several fictitious

companies, collectively referred to as “Channel Partners,” to justify the need to be assigned

more IP addresses from ARIN. Golestan even invented fictitious individuals who he

represented were officers of the Channel Partners and submitted fraudulent documentation

to ARIN under the names of these fictitious individuals. Through the Channel Partners,

Golestan then began to request IPv4 addresses directly from ARIN. In total, Micfo and the

Channel Partners obtained approximately 1.3 million IPv4 addresses through this

fraudulent scheme.

Golestan sold some of the IPv4 addresses through third party brokers. Through this

scheme he made approximately $3.3 million in profits. When Golestan attempted to sell

the rights to additional IPv4 addresses, however, his criminal plot was uncovered. ARIN

“red flagged” Golestan’s attempt to sell $6 million worth of IPv4 addresses and blocked

the transfer of these IPv4 addresses. J.A. 217–18.

C. Procedural History

A federal grand jury indicted Golestan and Micfo, as a corporate defendant, on 20

counts of wire fraud, in violation of 18 U.S.C. § 1343.

1. Motion to Dismiss the Indictment

Golestan and Micfo moved to dismiss the indictment, arguing that it was defective

because it failed to allege facts that, even if true, could sustain a violation of the wire fraud

statute. Golestan and Micfo asserted that they did not obtain money or property by means

of false or fraudulent pretenses because IP addresses are not “property” within the meaning

of the wire fraud statute. The Government responded that the rights to use and assign an IP

5 USCA4 Appeal: 23-4592 Doc: 84 Filed: 08/22/2025 Pg: 6 of 21

address satisfies the relevant definition of property. The district court agreed with the

Government and denied the motion to dismiss.

2. Bench Trial

The parties proceeded to a bench trial, where Golestan and Micfo were represented

by the same defense counsel. During the first day and a half of trial, the Government

presented eight witnesses. Although defense counsel had repeatedly informed the court of

Golestan’s plan to present evidence to show that the Channel Partners were legally

recognized entities, his defense counsel subsequently stated that he was unable to produce

such evidence. Defense counsel asked the district court for time to confer with the

Government. Following a 30-minute break, Golestan and Micfo moved for a change of

plea from not guilty on all counts to guilty.

That same day, the district court proceeded with a plea colloquy.
