Clinical trial eligibility criteria: eligible ages (years): 18.0-999.0,  Metastatic Melanoma Recurrent Melanoma Stage III Cutaneous Melanoma AJCC v7 Stage IIIA Cutaneous Melanoma AJCC v7 Stage IIIB Cutaneous Melanoma AJCC v7 Stage IIIC Cutaneous Melanoma AJCC v7 Stage IV Cutaneous Melanoma AJCC v6 and v7 Unresectable Cutaneous Melanoma STEP 1 Eastern Cooperative Oncology Group (ECOG) performance status: 0 or 1 The effects of dabrafenib and trametinib or ipilimumab and nivolumab on the developing human fetus are unknown; furthermore, dabrafenib has been reported to interfere with the effect of hormone based oral contraceptives; for this reason and because other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential and sexually active males must agree to use at least two other accepted and effective methods of contraception and/or to abstain from sexual intercourse for the duration of their participation in the study, and for at least 4 weeks after treatment with dabrafenib or for 4 months after dabrafenib in combination with trametinib; women of child-bearing potential must use at least two other accepted and effective methods of contraception and/or to abstain from sexual intercourse for at least 5 months after the last dose of nivolumab and/or ipilimumab and sexually active males must use at least two other accepted and effective methods of contraception and/or abstain from sexual intercourse for at least 7 months after the last dose of nivolumab and/or ipilimumab; should a woman become pregnant or suspect she is pregnant while she is participating in this study, she should inform her treating physician immediately Patients must have unresectable stage III or stage IV disease Patients must have measurable disease; all sites of disease must be evaluated within 4 weeks prior to randomization Patients must have histological or cytological confirmation of melanoma that is metastatic or unresectable and clearly progressive NOTE: Any patient with BRAF V600 mutant melanoma (whether cutaneous, acral or mucosal primary) who meets the is eligible for participation in this trial; patients with uveal melanoma are not eligible for this trial Patients must have BRAF V600 mutation, identified by a Food and Drug Administration (FDA)-approved test at a Clinical Laboratory Improvement Act (CLIA)-certified lab; if test at CLIA-certified lab used a non-FDA approved method, information about the assay must be provided (FDA approved tests for BRAF V600 mutations in melanoma THxID BRAF Detection Kit and Cobas 4800 BRAF V600 Mutation Test, Foundation Medicine); prompt information on tumor BRAF mutation status can also be obtained via Novartis "knowNow" Program Patients may have had prior systemic therapy in the adjuvant setting; however this adjuvant treatment must not have included a CTLA4 or PD1 pathway blocking antibody or a BRAF/MEK inhibitor; also, patients may not have had any prior systemic treatment for advanced (measurable metastatic) disease Patients must have discontinued chemotherapy, immunotherapy or other investigational agents used in the adjuvant setting >= 4 weeks prior to entering the study and recovered from adverse events due to those agents; mitomycin and nitrosoureas must have been discontinued at least 6 weeks prior to entering the study; patients must have discontinued radiation therapy >= 1 week prior to entering the study and recovered from any adverse events associated with treatment; prior surgery must be >= 2 weeks from registration and patients must be fully recovered from post-surgical complications  Women must not be pregnant or breast-feeding, as the effects of ipilimumab + nivolumab or dabrafenib + trametinib on the developing human fetus are unknown All females of childbearing potential must have a blood test or urine study within 2 weeks prior to registration to rule out pregnancy A female of childbearing potential is any woman, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months) Patients must not receive any other investigational agents while on study or within four weeks prior to registration Patients are ineligible if they have any currently active central nervous system (CNS) metastases; patients who have treated brain metastases (with either surgical resection or stereotactic radiosurgery [SRS]) could be eligible; patients must not have taken any steroids =< 10 days prior to randomization for the purpose of managing their brain metastases; repeat imaging after SRS or surgical resection is not required so long as baseline magnetic resonance imaging (MRI) is within 4 weeks of registration; patients with multiple brain metastases treated with SRS (with [w] or without [w/o] whole-brain radiotherapy [WBRT]), are not an exclusion; patients with definitive CNS metastases treated with only WBRT are ineligible; patients with potential CNS metastases that are too small for treatment with either SRS or surgery (e.g. 1-2 mm) and/or are of uncertain etiology are potentially eligible, but need to be discussed with and approved by the study principal investigator (PI) Patients must not have other current malignancies, other than basal cell skin cancer, squamous cell skin cancer, in situ cervical cancer, ductal or lobular carcinoma in situ of the breast; patients with other malignancies are eligible if they have been continuously disease-free for > 2 years prior to the time of registration Patients must not have any serious or unstable pre-existing medical conditions (aside from malignancy exceptions specified above), including but not limited to, ongoing or active infection requiring parenteral antibiotics on day 1, or psychiatric illness/social situations that would limit compliance with study requirements, interfere with subject's safety, or obtaining informed consent; therapeutic level dosing of warfarin can be used with close monitoring of prothrombin time (PT)/international normalized ratio (INR) by the site; exposure may be decreased due to enzyme induction when on treatment, thus warfarin dosing may need to be adjusted based upon PT/INR; consequently, when discontinuing dabrafenib, warfarin exposure may be increased and thus close monitoring via PT/INR and warfarin dose adjustments must be made as clinically appropriate; prophylactic low dose warfarin may be given to maintain central catheter patency Patients must not have a history of or evidence of cardiovascular risks including any of the following QT interval corrected for heart rate using the Bazett's formula (QTcB) >= 480 msec. at baseline History of acute coronary syndromes (including myocardial infarction or unstable angina), coronary angioplasty, or stenting within the past 24 weeks prior to registration
