    UNITED STATES of America, Plaintiff-Appellee, v. Joe Kendrick HARDY, Defendant-Appellant.
    No. 16-13180 Non-Argument Calendar
    United States Court of Appeals, Eleventh Circuit.
    (January 6, 2017)
    Sandra J. Stewart, George L. Beck, Jr., Kevin P. Davidson, Tommie Brown Hard-wick, R. Randolph Neeley, U.S. Attorney’s Office, Montgomery, AL, for Plaintiff-Ap-pellee
    Patricia Vanessa Kemp, Brandon Thomas, Kevin L. Butler, Christine A. Freeman, Federal Defender Program', Inc., Montgomery, AL, for Defendant-Appellant
    Before WILLIAM PRYOR, JORDAN and ROSENBAUM, Circuit Judges.
   PER CURIAM:

Joe Kendrick Hardy appeals his sentence of 24 months of imprisonment following the revocation of his supervised release. Hardy argues that he was entitled to credit for time served in the custody of state officials before he was transferred to a federal' prison to serve his sentence for being a felon in possession of a firearm. See 18 U.S.C. § 3585(b). Hardy also argues that his sentence is substantively unreasonable. We affirm.

The district court lacked authority to credit Hardy for time he allegedly served in state custody. See id. After a defendant begins serving his sentence, the Attorney General, through the Bureau of Prisons, has exclusive authority to determine whether the defendant has spent time in official detention and to compute the amount of credit' to which he is entitled. Dawson v. Scott, 50 F.3d 884, 889 (11th Cir. 1995). The Attorney General “make[s] the determination as an administrative matter when imprisoning the defendant.” United States v. Wilson, 503 U.S. 329, 335, 112 S.Ct. 1351, 117 L.Ed.2d 593 (1992). If Hardy had been “dissatisfied with the computation of [his] sentence [for being a felon in possession of a firearm, he had to] pursue the administrative remedy available through the federal prison system before seeking judicial review of his sentence.” United States v. Flanagan, 868 F.2d 1544, 1546 (11th Cir. 1989).

During his revocation hearing, Hardy did not request judicial review of the denial of credit; instead, he requested that the district court exercise “equitable consideration” and reduce his sentence under section 3585(b). But the district court could not award Hardy credit or take into account the time he allegedly served in determining what sentence to impose for his multiple violations of the conditions of his supervised release.

The district court did not abuse its discretion by sentencing Hardy to 24 months of imprisonment. Hardy had a criminal history category of VI when he was convicted for possessing a firearm as a felon and within six months of completing his prison sentence, he had, the district court stated, “made a mockery of [the] intention[s] [of supervised release].” Hardy violated the condition that he remain in Alabama by traveling to Tennessee, where he was cited for the misdemeanor offense of possessing synthetic cannabinoids and later failed to appear for a hearing on the charge, see U.S.S.G. § 7B1.1(a)(3) (identifying violations of state law and of conditions of supervised release as Grade C violations). Three months later, Hardy travelled unlawfully to North Carolina where he purchased and transported in a rental vehicle 33 pounds of synthetic cannabis from New York, for which he later was convicted of trafficking synthetic marijuana. See id. § 7B1.1(a)(1) (identifying controlled substance offenses as Grade A violations). Although Hardy faced a minimum sentence of 33 months under the advisory guidelines, the statute governing revocation limited his penalty to 24 months of imprisonment, see 18 U.S.C. § 3583(e)(3). The district court reasonably determined that the maximum statutory sentence best addressed, in its words, “all the factors contained in 18 U.S.C. Section 3553.” Hardy’s sentence is reasonable.

We AFFIRM Hardy’s sentence.
